I have a rudimentary mud client in elisp I cobbled together and use
(since emacs23 or so): It's been stable since then. However since
upgrading to emacs25 I've seen 4 crashes of emacs itself - 3 yesterday
and 1 today.
At first I thought perhaps it was keyboard/input related as it seemed
to happen while I was typing, but today while running the client
to see if I could track down the problem emacs segfaulted while
I wasn't typing or using the mouse. I managed to get a backtrace
out of gdb, which I have attached. I can semi-reliably reproduce
the crash.
I haven't been able to run xbacktrace as it hasn't yet crashed while
gdb was attached.
Looking at the backtrace and examining the source, it looks like
it blows up in the maybe_gc inside funcall _just before_ the first
hook in window-scroll-functions is called.

Anything in particular you want done when it triggers again?

Just backtrace is fine. But please try not to end the GDB session
immediately, because I might want to ask you to do something before
exiting GDB.

Triggered the segfault: Looks different to the emacs 25.1 fault
but still GC related, I think.
gdb session remains up and running.

Thanks, that seems okay.
Hmm... all those "optimized out" variables really make it hard
figuring out which Lisp data structure causes the trouble. Do you
know how to examine marked objects stored in the last_marked[] array?
There are some instructions about that in etc/DEBUG.

Yeah, I've come to loathe that "optimized out" message on other
projects too.

I'll have a look.

One thing to try is to rebuild Emacs without optimizations (-O0
compiler option).

Thank you. Let me know if you need help in that.

I'll kick off a build, but from experience that seems to help a lot
less these days - AIUI anything left in a register over a function
call still counts as optimised away, and you have to crack out
the disassembly instructions in gdb to see it. I'm guessing amd64
having a lot more registers makes this more obvious than in the
old i386 register-starved days.

Looks reasonable enough. Is there anything in particular you're
interested in, other than which object triggered the SEGV?

IME, it actually helps a lot, even on 64-bit machines.

The faulty object would be a very important clue. Once we find that
out, we should look at how that object is created and modified.
Thanks.

Not sure I'm doing this right, but here's what I have so far:
SEGV @
#0 mark_object; alloc.c:6450
last_mark_index=12, therefore last_mark[11] must be what we are looking at.
(gdb) p XTYPE(last_marked[11])
$41 = Lisp_Symbol
(gdb) p XSYMBOL(last_marked[11])
$44 = (struct Lisp_Symbol *) 0x3c382c0
(gdb) p *XSYMBOL(last_marked[11])
Cannot access memory at address 0x3c382c0
which matches alloc.c:6540 which is inside a `case Lisp_Symbol:' section
line that fails is:
if (ptr->gcmarkbit)
so we have a duff symbol?
============================================================================
#1 mark_object; alloc.c:6543
inside a case Lisp_Cons:
mark_object (ptr->car);
assuming this is the previous marked object:
(gdb) p XTYPE(last_marked[10])
$45 = Lisp_Cons
(gdb) p XCONS(last_marked[10])
$46 = (struct Lisp_Cons *) 0x2eaf810
(gdb) p *XCONS(last_marked[10])
$47 = {car = 50828624, u = {cdr = 48953347, chain = 0x2eaf803}}
(gdb) p XTYPE(50828624)
$49 = Lisp_Symbol
(gdb) p *XSYMBOL(50828624)
Cannot access memory at address 0x3c382c0 // curses, foiled again
============================================================================
#2 mark_maybe_object; alloc.c:4743
Not interesting: checks for alive-ness and calls mark_object
============================================================================
#3 mark_memory (end=0x7fffffffe218, start=<optimized out>); alloc.c:4895
for (pp = start; (void *) pp < end; pp += GC_POINTER_ALIGNMENT)
{
mark_maybe_pointer (*(void **) pp);
mark_maybe_object (*(Lisp_Object *) pp); // ← this is the entry point
}
(gdb) p XTYPE(*(Lisp_Object *)pp)
$63 = Lisp_Cons
(gdb) p *XCONS(*(Lisp_Object *)pp)
$65 = {car = 48892595, u = {cdr = 49727219, chain = 0x2f6c6f3}}
This doesn't seem to match what we encounter two frames down in mark_object:
Maybe I've misinterpreted something? Anyway:
following the earlier call to mark_maybe_pointer:
(gdb) call mem_find(*((void **) pp))
$86 = (struct mem_node *) 0x2cce8a0
(gdb) p *(struct mem_node *) 0x2cce8a0
$87 = {left = 0x2cce8e0, right = 0x2e816e0, parent = 0x2d5cb00,
start = 0x2f6c400, end = 0x2f6c7f0, color = MEM_BLACK, type = MEM_TYPE_CONS}
and later on:
case MEM_TYPE_CONS:
if (live_cons_p (m, p) && !CONS_MARKED_P ((struct Lisp_Cons *) p))
XSETCONS (obj, p);
break;
so we've copied the cons cell into obj (I think).
And then finally:
if (!NILP (obj))
mark_object (obj);
so maybe last_marked[9] is involved?
idx 9 seems to be a list with every car being:
(gdb) p last_marked[9]
$120 = 48953379
(gdb) p XTYPE(last_marked[9])
$121 = Lisp_Cons
(gdb) p *XCONS(last_marked[9])
$122 = {car = 8760836, u = {cdr = 48953363, chain = 0x2eaf813}}
(gdb) p XTYPE(8760836)
$123 = Lisp_String
(gdb) p *XSTRING(8760836)
$124 = {size = 4, size_byte = -1, intervals = 0x0,
data = 0xb374bb <pure+2999995> "DEAD"}
So... a reaped list? Not helpful anyway. Nothing identifiable here.
============================================================================
#4 mark_stack
Nothing of note here
============================================================================
Going up the backtrace all I find is that we're in the modeline display
code and we're _about_ to eval the mode-line-frame-identification
value:
(:eval (mode-line-frame-control))
But GC happens before we actually call it.
Not sure where to go from here: Any advice?

I think you should go back along last_marked[] and look for some valid
identifiable object.

Indeed. The exact evaluation is not really relevant because the
problem is with an object Emacs is trying to mark, which is most
probably unrelated to what's involved in the :eval form.

idx 7 is a cons, the car is integer 273081 (probably a buffer size
or char position), the cdr is a cons whose car is another instance of
DEAD
(gdb) p last_marked[7]

$293 = {size = 4, size_byte = -1, intervals = 0x0,

idx 6 seems to be a marker (I guess?) inside a cons:

From here on things don't look interesting (to me) but included for
completemess: just character positions, cons cells, small chunks of text
and the symbol nil.
Would recompiling the the GC sanity checking turned on be useful here?
How hard would it be to make emacs log the pointer or pseudopointer and
context when creating an object to stderr so we could figure out which
object got corrupted? I guess we'd be swamped by output, especially as
it can take a long time to trigger the bug.

The old code in lui.el used to (effectively) do this:
(setq buffer-undo-list (mapcar a-lambda-here buffer-undo-list))
This seemed to cause some strings in the undo list structure to get
freed to early, then freed again later.
The altered code uses the approach of setf'ing the relevant elements of
the undo-list, which doesn't trick the GC code into a premature free.
Since there's a workaround it's not particularly urgent, but it seems
to me that there's a hole in the GC logic somewhere.

If I understand correctly, the external lui package set buffer-undo-list
to something invalid, and this led Emacs to segfault when gc-ing?
Was there any further work done here, or a reproducible test case
written?

Not invalid as such - entries were removed from the list while it was "in
flight" through a mapc/mapcar and a double free (or similar) occurred.

No test case was written, the code for lui was changed to operate on
a copy of the undo list, then assign that back to the original head
variable instead.

You can make the Emacs gc segfault pretty trivially by making lists that
are recursive in just the wrong way, but it'd be interesting to see just
what it was that lui.el was doing. But if there's no test case, then it
seem unlikely that we'll make further progress on this bug report.
So I'm closing this bug report. If further progress can be made, please
either open a new bug report or respond to this and it'll be reopened.
