=============================================================================
In Emacs 28 and Emacs 29, desktop-load crashes when there are too many
iconified frames in the .emacs.desktop file.
The two attached .emacs.desktop files show the smallest test case that
I could come up with:
- .emacs.desktop.works with 3 non-iconified and 4 iconified frames
loads without problem in Emacs 28
+ desktop-load of this file crashes in Emacs 29.1
+ a .emacs.desktop with 3 non-iconified and 3 iconified frames works
in Emacs 29.1
- .emacs.desktop.crashes with 3 non-iconified and 5 iconified frames
leads to a crash in Emacs 28 (see attached problem report generated
by macOS)
- I tried .emacs.desktop with up to 17 non-iconified frames in Emacs
28 without problems
- Up to Emacs 27, I've never seen a problem with desktop-load crashing

Thanks, can you run Emacs 29 under a debugger and show a backtrace
when it crashes?

Unfortunately, I don’t have a C development environment setup on my little MacBook (and haven’t used gdb for more than 20 years besides).

Backtrace from LLDB will be also helpful. Without a crash backtrace,
we will have to wait until someone can reproduce the crashes on a
system where a debugger _is_ available.

Can you please try the master branch with the two attached patches
applied? The v2 patch should be applied first.
The apple crash report is enough to see that the crash is happening
somewhere deep inside the AppKit code on frame creation. No idea why,
but maybe we'll be lucky and the fix will be the same as the last
frame-creation crash fix...

Alas, I cannot reproduce the abort here, with an unpatched master or
emacs-29, and neither on Ventura/arm64 nor Big Sur/x86_64 :-(.
Christian, can you reproduce this with emacs -Q? Or does it perhaps
depend on your init.el? (This was the case for me in the child frane
case that Alan fixed.)

It took me a while to get lldb to run emacs (missing get-task-value entitlement), and then:
running under lldb, emacs doesn’t crash, but it also doesn’t open any frames:
> lldb /Applications/Emacs-28.2.app/Contents/MacOS/Emacs
> (lldb) target create "/Applications/Emacs-28.2.app/Contents/MacOS/Emacs"

> (lldb) ^D
Without lldb:

> Fatal error 11: Segmentation fault
> Abort trap: 6
Could you please give me a hint, how to start Emacs under lldb so that it behaves the same as if started interactively ?

Thank you for your efforts.
Gerd, could you perhaps help Christian reproduce this under LLDB and
produce a useful backtrace? He needs to run Emacs so as to restore
the desktop saved on the .emacs.desktop file.
Thanks.

Emacs29 -Q also crashes, but differently:
/Applications/Emacs-29.1.app/Contents/MacOS/Emacs --load=emacs28_desktop_load_init.el
Fatal error 11: Segmentation fault

Emacs28 -Q doesn’t crash:

Fatal error 11: Segmentation fault
Abort trap: 6
/Applications/Emacs-28.2.app/Contents/MacOS/Emacs -Q --load=emacs28_desktop_load_init.el
### no crash, desktop-read works
Weirder and weirder …
I tried to come up with a simpler desktop to trigger the crash, but 8 frames with the *scratch* buffer, 4 iconified, are not enough to trigger it.
OTOH, opening two empty files 1 and 2 with 4 frames for each one and two frames of each file iconified triggers the crash in Emacs29 without the ‘-Q’, so only with my init-file involved.
Gerd, did you test with the .emacs.desktop files I attached to the bug report? My environment configures desktop-save to save iconified frames which standard Emacs doesn’t do. I have only seen crashes where there were more than 3 or 4 iconified frames in the .emacs.desktop.

Could you please tell which LLDB this is
lldb --version
and how you installed it? The missing entitlement is strange.

This looks correct to me. Let's first see what's up with this lldb.

It doesn't seem to happen everytime, and to make things weirder,
I didn't get it to abort under lldb.
Guess I'll build an emacs-29 with all checking bells and whistles now.
I come back to you when I find something out.

lldb --version
lldb-1205.0.27.3
Apple Swift version 5.4 (swiftlang-1205.0.26.9 clang-1205.0.19.55)
I didn’t install lldb itself, but I assume it was installed together with the Xcode command line tools.
The entitlement seems to be a frequent issue but it is very hard to find in DuckDuckGo.

That's good, indeed. (You could also get the Xcode command line tooks
with
xcode-select --install
but I guess that's not necessary, unless you need them for something
else.
> Except for Emacs exiting without doing anything?
Yeah. That's strange. Emacs is starting normally, here. Some frames
open, some of them are iconified ...

That's gonna be a bit more difficult than I thought. With ASAN,
CFLAGS = -g -O0 -fsanitize=address -fno-omit-frame-pointer
the abort does not happen when run 100 times, like so
#! /usr/bin/env zsh
for i in {1..100}; do
~/emacs/29/src/emacs -Q --eval '(desktop-read "~/bug-sowieso")' --eval '(kill-emacs)'
done
I'll have to let that sink in a bit, to get an idea how to preceed.

I've a vague memory that I've seen something like this before and it
was a runaway loop corrupting the heap...

Cool: If a build with ASAN, but with -O2 and leave out
omit-frame-pointer, the abort happens, with enough tries, but ASAN isn't
triggered. So, I guess it's not something in Emacs' code.

Sometimes one just has to be lucky enough :-).
This is with the "-g -O2" build.
Does this tell you anything?

Is this the same error as above, with the corrupt autorelease pool?

This is an interesting little bit of code with a comment saying it's
been added to cover for what sounds like a bug in macOS 10.10...
Perhaps it's worth removing it and seeing if that helps.
The code's around nsterm.m line 4569, and the whole #ifdef'd section
should be removed.
I still suspect that if we have a corrupt autorelease pool, the
problem will be somewhere entirely different...

Probably not, one being an ABRT, and one a SEGV. Or maybe they are,
if the underlying cause is the same.
It's all pretty strange. Maybe it's a timing thing? I mean, ignoring
the possibility of an optimization bug for a moment, the fact that
optimization flags that make Emacs slower make the bug disappear. Or
the fact that it takes a "random" number of runs to make it happen. And
that it doesn't happen at all on my old Macbook, which is 2x or so
slower than my M1 Mac mini. I wouldn't be surprised if Christian had an
even faster CPU, so that he sees the bug more reliably.
Out of curiosity, Christian, what CPU do you have?

Yeah. Strange thing is that ASAN doesn't kick in. Hm. Maybe Apple has
something for debugging such situations? I guess it's worth googling.

If you guys ever come to Portugal, give me a call. The beer’s on me.

OK, I've pushed this change to master.
Christian, would you mind making sure it fixes the issue on your
machine too?

Unfortunately, I currently only have a small-disked MacBook with no compilation environment.
I’ll have to wait for the Emacs 29.2 …
In the mean time, I might have an idea how to mitigate the issue.
Thanks again !

OK, thanks. I'll just close this now then.

Yup. That worked.
I defined one hook added to desktop-save-hook and another one added to
desktop-after-read-hook. The idea is to have no iconified frames in
the .emacs.desktop, so ::
+ the hook running before desktop-save makes all iconified frames
visible and sets a frame-parameter to mark the frame is iconified
(defun lse-frame:desktop-before-save:deiconify-frames ()
"desktop-save-hook: de-iconify all frames that are iconified"
(dolist (frame (frame-list))
(when (eq (frame-parameter frame 'visibility) 'icon)
(set-frame-parameter frame 'lse-iconified t)
(make-frame-visible frame)
)
)
)
+ the hook running after desktop-read iconifies all frames marked by
the desktop-save-hook
(defun lse-frame:desktop-after-read:iconify-frames ()
"desktop-after-read-hook: iconify all frames that were de-iconified
before desktop-save"
(dolist (frame (frame-list))
(when (frame-parameter frame 'lse-iconified)
(set-frame-parameter frame 'lse-iconified nil)
(iconify-frame frame)
)
)
)
A fringe benefit of this is that position and size of iconified frames
are preserved better.
An .emacs.desktop that crashed will work after being changed from
`(visibility . icon)` to `(visibility . t) (lse-iconified . t)`.
So I can upgrade from Emacs 27 to Emacs 28.2.
Emacs 29.1 is still out because of bug=65840.
Cheers,
