Package: Emacs
Version: 24.0.50
My Lucid build of Emacs crashes right at the start before any frame gets
opened (emacs -nw works fine):
(gdb) r -Q

I can't reproduce this. I used your configure flags, and tried with Xaw3d and
straight Xaw. I guess it is some memory corruption or aligment problem. Can
you compile without Xaw3d and just use standard Xaw? You don't have that gcc
4.4 memcpy bug? Does it happen wih -O0 also?
If you compiled Xaw3d yourself, recompile it with debug and run gdb to the crash.

Now, I sometimes can and sometimes can't. Still investigating.

I saw it on all my machines (tho admittedly, they're all running pretty
much the same Debian testing). I tried "xrdb -remove" but it didn't help.
> Can you compile without Xaw3d and just use standard Xaw?
You mean without-toolkit-scroll-bars? Good idea...
Hmm... configure still says "Does Emacs use -lXaw3d? yes".
But I'm not sure yet if it helps (I haven't seen it crash
without-toolkit-scroll-bars, but since then I haven't seen it crash on
that same machine with Xaw3d scroll bars either).
> You don't have that gcc 4.4 memcpy bug?
You mean the 4.5 bug? No, I have Debian's 4.4.2.
> Does it happen wih -O0 also?
Yup.

The crash I showed was with a hand-compiled Xaw3d with debug info
(actually an Xaw3d with some local changes so that you can dynamically
choose the Xaw-style or the motif-arrow-style scrollbars). But the
backtrace is in Xt code, not in Xaw(3d) code.

XtInitializeWidgetClass (where it crashed), fills in the widget class
structure. I guess something in the widget description is wrong, such as
saying sizeof(int), where sizeof(double) is intended, or OffsetOf points to
the wrong member. If you have local changes, there is a good place to start
looking.
This is hard to see without a debug compiled Xt. Doesn't Debian have separate
debug-infos that you can install for Xt?

Any luck debugging, or did the problem go away?
