Hello.
Sometimes I get a segmentation violation and emacs dies.
I just managed to catch it in the debugger. Backtrace below (very long,
but instructions says to give bt full),
Let me know if you need more info, I'll keep it in the debugger for a
couple of days. This is from trunk, updated and built today (Apr 7, 2010).
Program received signal SIGSEGV, Segmentation fault.

Ouch! My bad, probably.
First, what caused the crash? I think it's BUFFERP, so please tell
what is glyph->object.
Also, can you tell something about what were you doing at the moment
of the crash? It looks like you were typing in the minibuffer, is
that correct?
Finally, what does the GDB command "pgrow" print?
Oh, btw: is this an optimized or an unoptimized build?

It is correct, I did C-x b and typed an x in the minibuffer when the crash
occurred. The contents of the minibuffer is two lines.

Yep, it's an invalid object, somehow. I wonder how did that happen...
(Btw, in a crashed session, it is not safe to use pp and pr: they call
functions in Emacs, which could themselves crash, depending on the
extent of damage caused by the original crash. It is better to use
"xtype" followed by an xSOMETHING command, where SOMETHING depends on
what "xtype" prints; for example, "xbuffer" if "xtype" says the object
is a buffer.)

And it looks like you are using some optional feature for minibuffer
completion? IOW, what should I do in "emacs -Q" to see the possible
completions as I see them in the output of "pgrow", viz.
Switch to buffer (default xsettings.h): x(settings.c,lwmenu.c,lwmenu.h,fns.c,te
I'd like to try to reproduce this problem.
Thanks.

This can take some time. Emacs crashed for me, and then I restarted it from
gdb. It took about 3 hours before it crashed again, and I'm sure I've made
many C-x b in that time.

How many of these "C-x b"s caused the list of possible completions to
exceed one screen line? If the answer is "many" or "all", then could
you try to figure out or recall if there was anything special about
the ones that caused crashes?

Somewhere between "many" and "all". It is the same list of files I was
editing. They mostly start on x (xsettings, xtern, xfns, xlwmenu, and so on),
so it probably looked pretty much the same each time.
There was nothing special about the one that caused a crash I can think of.
It seems it just takes time. I just got a crash again, but this time I hadn't
started it from gdb, unfortunately. Also, about 3-5 hours before it crashed
this time.

I think I found the problem. The invalid glyph that caused the crash
was not supposed to be dereferenced. Its pointer is exactly the same
as `end', as your backtrace shows:
#0 0x000000000044d2f1 in set_cursor_from_row (w=0x1378d60, row=0x1fbf550,
matrix=0x18217a0, delta=0, delta_bytes=0, dy=0, dvpos=0) at
/home/jhd/src/emacs/fixes/src/xdisp.c:12775
glyph = 0x1fa5cd0
end = 0x1fa5cd0
But `end' points beyond the last glyph in the TEXT_AREA of the glyph
row:
struct glyph *end = glyph + row->used[TEXT_AREA];
If we dereference this pointer, we could be referencing uninitialized
memory, e.g. if there are no margins (i.e. no glyphs in the row after
TEXT_AREA).
The old code was careful not to dereference such a pointer, but when I
rewrote set_cursor_from_row, I failed to copy those precautions.
I installed a fix. Please see if it stops these crashes, and if so,
please close the bug report.
Thanks.

Great! I'll run for a couple of days and if it doesn'r reappear I will close
the bug.
