You reported

    Unfortunatly, I get a segfault in the next step.  Any idea how to go
    about debugging this issue?

    ./temacs --batch --load loadup bootstrap

Could you please try running temacs under GDB and starting
with `r temacs -batch loadup'?  Please report the backtrace,
and then please try investigating the cause of the crash
by examining relevant data values in the innermost frame.

Does anyone else have a ppc mac to debug this on?

Unfortunately that gives no useful clues.

Next step: try deleting forms at the end of files.el,
one by one, and seeing when the crash stops happening.
The next form is the one that causes the crash.
Can you show us that one?

I just discovered that running ./temacs --help also segfaults, with a
more useful backtrace.

I deleted forms all the way until files.el was an empty file, and it
crashes the same way, with no useful backtrace.

I'm not sure this is informative, because that also segfaults for me,
yet I can build emacs with no problems.

I deleted all the forms in files.el and it still crashes, with the
uninformative backtrace:

    Program received signal SIGSEGV, Segmentation fault.

    (gdb) #0  0x00000000 in ?? ()

I wrote on the list that ./temacs --help also crashes, which you said
was probably unrelated, and I believe that others here said it does
that for them too, on other platforms.

--help crashes because init_obarray() hasn't been called, which in
turn means that Vobarray is NULL.  Since Vobarray is NULL, emacs will
segfault when doing intern("emacs-version") at
emacs.c:bug_reporting_address().

I'll try to debug this, thanks to Ryan for giving me access to the
machine where this goes belly up.

I have a useful backtrace for this problem, but I can't really figure
out why it happens.  The short story is that the problem is caused by:

(setq load-source-file-function 'load-with-code-conversion)

in loadup.el, this causes insert-file-contents to be run from mule.el,
at which point when we are returning from insert-file-contents,
something corrupts the stack, so that we cannot return, and we
segfault badly because of it.

If one simply doesn't set load-source-file-function, we continue quite
far until trying to load faces.el, at which point temacs complains
about requiring 'cl.

I have attached a (messy) backtrace; this is right at call to
insert-file-contents in mule.el on line 78, and we are just returning
from insert-file-contents.  Does anyone know what is going on?

    I deleted all the forms in files.el and it still crashes, with the
    uninformative backtrace:

Please try it with a breakpoint at Fload.  It will get there for each
file that is loaded.  Since each file prints a message, you will be
able to tell from the previous message when it is there for files.el.

Then step through the function and its subroutines, and you can
observe how it crashes.

       I wrote on the list that ./temacs --help also crashes, which you
       said was probably unrelated, and I believe that others here said it
       does that for them too, on other platforms.

    --help crashes because init_obarray() hasn't been called, which in
    turn means that Vobarray is NULL.  Since Vobarray is NULL, emacs will
    segfault when doing intern("emacs-version") at
    emacs.c:bug_reporting_address().

I don't think it is urgent to make temacs --help work.

      The short story is that the problem is caused by:

    (setq load-source-file-function 'load-with-code-conversion)

I think it is misleading to say the problem is caused by this code,
since this code is both correct and totally necessary.  The problem is
caused by a bug somewhere else.

    at which point when we are returning from insert-file-contents,
    something corrupts the stack, so that we cannot return, and we
    segfault badly because of it.

That is the bug we have to find and fix.

You are of course correct.

Yes, but how?  I don't actually think that this bug is in Emacs, but
in OpenBSD.  I compiled Emacs using -ggdb3, just so I could get some
more detailed data, but that to my suprise that worked like a charm
(my network connection died in the middle when compiling .elc files,
so it did atleast dump emacs).
 
I'll investigate some more, but I don't think it is something that can
be fixed in Emacs, since from the looks it is something to do with how
OpenBSD/macppc does stack protection.

Ryan, could you resend me the login data for your macppc box? I lost
it when my network connection died (don't know if you saw my message
on IRC).

That surprises me.  I thought that -g options did not change
the generated code.

This could be an Emacs bug instead of a libc bug.
Either way, the only to make progress is to track it down.
Using stepping and breakpoints, you can narrow down the place
where the problem happens.  Eventually you will find a specific
line that clobbers the stack.  Then you will see either that it
is a libc function, or some code in Emacs itself.

Ok, I have narrowed down the problem to being a problem in GCC, not in
Emacs.  Emacs compiled with "-g -O2" (the default) does not work,
while -O1 does.  This also explains why -ggdb3 worked, I never passed
a optimisation switch, so Emacs was compiled without optimisations.

Exactly which optimisation switch causes this, I don't know, nor do I
have much time to follow up on this anymore, but if it you think it is
important I can try and look at it some more.  I suspect it has
something to do with how callers are saved or something.

Mentioning the problem in etc/PROBLEMS would be enough I think.  Ryan
will also try and get a machine running a newer version of OpenBSD to
see if the problem persists there.

Which GCC versions does this fail with?  Does it fail with the latest
GCC version?  If so, we had better track it down so as to make a good
GCC bug report.

For this Emacs release, we can deal with it with a note in
etc/PROBLEMS.  But that note should say whether upgrading GCC is a
solution.

So would someone please try installing the latest GCC release
and see?

As a note aside: GCC 4.2 has just been released a few days ago.

I will see how things build with this later version and report back
here in the next day or so.

OpenBSD uses their own heavily patched version of GCC, which is quite
old (3.3.5) compared to our version (4.2.0).  For all I know, it can
be a bug that only exists in OpenBSD's GCC, and not in our GCC.

   For this Emacs release, we can deal with it with a note in
   etc/PROBLEMS.  But that note should say whether upgrading GCC is a
   solution.

I don't think this is a very important thing to mention, upgrading GCC
just to compile Emacs seems like a lot of work.  Not to mention that
GCC 4.2.0 that was just released doesn't compile on OpenBSD 4.0 (to
atleast my great suprise).

This still does not imply that the bug is in GCC rather than in Emacs.

Do we still also need some kind of fix so that -znocombreloc or
-nostdlib is passed to the linker on this platform? Possibly taking
out the

#if defined(__OpenBSD__)
#define ORDINARY_LINK
#endif

in src/m/macppc.h?

Yeah, removing that is still needed, thanks for keeping that in mind.
I think that this should be done for src/m/alpha.h as well.

I installed some PROBLEMS text (feel free to tweak), and deleted the
ORDINARY_LINK from macppc.h. I left alpha.h alone because I'm not
aware of any problems reported there, though that may just be because
no-one uses that platform.

I'm quite sure that it is a problem, despite not having this
particular platform.  Also, OpenBSD has such a patch locally for Emacs
21.
