Last week I updated to the trunk version and now Emacs crashes once or
twice a day.  As far as I can tell, I don't do anything unusual when it
happens: just reading and moving up and down with the cursor keys.  This
happened in c-mode, lisp-mode and I think even in man-mode.

I now start Emacs with (ulimit -c unlimited && emacs)& and have a core
file.  The output of "bt full" is below. xbacktrace didn't show
anything, but I'm not sure if I sourced the .gdbinit correctly.

This is my configuration:

In GNU Emacs 24.0.50.2 (i686-pc-linux-gnu, GTK+ Version 2.20.1)

Please try reproducing this in an unoptimized build.  Backtraces from
optimized builds are useless for debugging.  It looks like it->f is
NULL in frames #4 and therefore in frame #3, which is the cause of the
crash.  But I don't believe anything GDB displays in optimized builds,
not even to backtraces.

I updated the source tree and configured with
`configure  '--with-gif=no' '--with-gnutls=no' 'CFLAGS=-g3 -O0''

Then started Emacs from gdb.  After a while the it occurred again.
it->f seems to be 0 here too:

Please reconfigure like this:

  configure --enable-asserts --enable-checking --with-gif=no --with-gnutls=no 'CFLAGS=-g3 -O0'

This will enable several important sanity checks and hopefully allow
us to see why the frame pointer is NULL.  Please try again after
rebuilding Emacs, and see if you get an abort somewhere, or the same
segfault.

If you go up 1 frame to here:

> #1  0x080865e7 in redisplay_internal () at xdisp.c:12814

And display w->frame there, is it also NULL?  If so, can you display
the contents of the structure pointed to by w, and also compare that
with selected_window?  Also, what is the value of current_buffer and
selected_frame?

When this happened, is it possible that you did something that
modified the display configuration, like killed a window or a frame or
changed the display dimensions?

I don't think we can trust any crash backtraces from the 64-bit
Cygwin-w32 builds until we understand what happens with the assertion
violations in bidi.c.

Let's try anyway (assuming you still have this in a debugger):

> #0  0x0000000100650249 in composition_update_it (cmp_it=0x226a98, charpos=1819, bytepos=1819, string=4306700338) at composite.c:1322
>         cmp = 0x226240
>         i = 0
>         c = 2272050

Please show what these commands print in GDB:

 (gdb) frame 0
 (gdb) p *cmp
 (gdb) frame 1
 (gdb) p it->cmp
 (gdb) p it->current

And I imagine that your buffer was pure-ASCII (is that right?), so no
compositions are involved and we probably shouldn't be even entering
composition_update_it at all.

More information was requested, but no response was given within a few
months, so I'm closing this bug report.  If the problem still exists,
please reopen this bug report.
