Hello,
I've built 24.1 release and the latest version from git repository.
Both exhibit same behavior:

Things that might need clarification:
- I try to avoid AA fonts everywhere I can, so, every possible font
rendering setting I found is set so it shouldn't use AA. This is KDE
on Debian squeeze 64 bit. The default font used everywhere is Arial.

What I see when Emacs starts (and stops on the fault) - the display
area isn't fully initialized, the screen and the scrollbars aren't
drawn completely (scrollbars show blanks). The mouse pointer changes
shape to a bitmap image of an arrow (similar to the one used on Macs,
i.e. black arrow with white contour) while hovering over the menu
strip. The mouse pointer disappears when hovering over the text area.
The menu in Emacs doesn't use the system default font at the time it
crashes (it uses something that looks like narrow-ish Helvetica, but
cannot tell for sure, but it uses some sort of vector rendering, it's
not a bitmap font.)

I'll happily provide any additional info.

Best.

Oleg

Is the reason for SIGSEGV that s->font is a NULL pointer?  If not,
what is the reason?

Please type "bt full" at the GDB prompt when Emacs crashes, and post
here the results.  (If you type "set logging on" before that, GDB will
output everything to a file named gdb.txt in the directory where you
run it, so you won't need to copy from the screen.)

Also, if you built Emacs with optimizations, please reconfigure and
rebuild like this:

  CFLAGS='-O0 -ggdb -g3' ./configure --enable-checking --enable-asserts ...
  make

(where "..." stands for any other options you use with configure).
This is because backtraces from optimized builds are deceptive and
make debugging hard.  If you do make a new build without
optimizations, please make sure it crashes like the optimized one.

Thanks.

I've reset the flags to no optimization and recompiled, and I see the
same error. Below is the full log, I'll paste it here in case the list
doesn't accept attachments, sorry if it will come out crooked.

       Inferior 1 [process 27265] will be killed.

Quit anyway? (y or n)

As an aside, I also tried to compile it with no XFT support, with the
same result. When configuring for this compilation I didn't add any
more options, just the --enable-checking --enable-asserts.

Best.

Please go to the above stack frame:

  (gdb) frame 2

and then display the glyph_row 'row':

  (gdb) pgrow

and post here what it shows.

The 'pgrow' command is defined on src/.gdbinit, so either start GDB
from the src/ directory (so it reads .gdbinit automatically), or type

  (gdb) source /path/to/src/.gdbinit

before invoking the 'pgrow' command.

I leave the rest of the backtrace, to get it recorded by the bug
tracker.  Please always CC 11813@debbugs.gnu.org when you mail
responses about this bug.

This is the mode line (of the "*scratch*" buffer, I presume).  The
GLYPHLESS parts seem to indicate that Emacs has no font to display the
buffer name in bold.  Is that possible, given your configuration of
fonts?

I'll try to find a way to avoid a crash in this case.

By the way: is this on a TTY or in a GUI session?

This is the GUI session.

It's not impossible, if I knew what font it is looking for I'd know
for sure. I had some problems before with multilingual support and
added fonts on the case by case basis, those I could find. Although
Emacs23 I have from PPA starts fine with the fonts I have. Correct me
if I'm wrong, but Emacs doesn't seem to read fonts.conf from my user
directory - how would I set it to use certain fonts?

Best.

That was a stupid question on my part, sorry.

Sorry, I don't know, I don't have experience with GTK and related
environments.

Could you try the patch I just posted and see if it solves the issue
at hand?

The file font.conf is used by fontconfig and not related to Gtk. Fontconfig is used for all aa-fonts on X11.

Hi, sorry for delay.

I've applied the patch, and it looks like the initial problem is
fixed, however, the other problem, which seems related surfaces. Below
is debugger output (I've compiled w/o optimization flags).

If I may suggest, I don't know the code very well, but, could it
assert on whether the font exists or not and print out somehow what
font it is looking for? That might be even better then accounting for
non-existing fonts later on.

One more clarification, this is not GTK, I'm running KDE 4.4.5.
Perhaps, although unlikely, I have to change something in it's fonts
configuration? (not that I know of such, but if you do, you are
welcome to suggest).

Best.

Oleg
