--with-pgtk crashes

[T.V Raman]

Latest build from head with --with-pgtk now crashes on Linux (Debian)
when started under X.


Taking out the --with-pgtk and rebuilding works fine.

Can you post a backtrace from the crash, please?  That will make
finding the culprit much easier and faster.

Thanks.

It doesn't yield a backtrace -- even if started with --dbug-init ---
basically emacs launches, then the window disappears -- it dumps some
debug addresses in .xsession-errors but they dont look meaningful.

Please run Emacs under GDB, and show a backtrace from that.

Thanks.

FWIW, I'm on wayland with PGTK enabled and it's working just fine.  When
I explicitly state that it should run unter xwayland instead using

  env -u WAYLAND_DISPLAY emacs -Q

I get no crash but except for the mode-line and menu-bar nothing is
displayed/rendered, that is, the scratch buffer is and stays empty and
so is the echo area.  There's also no tool-bar.  I can see that emacs
reacts, e.g., `C-h i' will open info which I can see because the frame
changes its title.

Oh, well, when I resize the emacs frame a bit (I'm using a tiling
compositior), out of sudden all those missing things appear. :-)
So I guess that's a separate issue.  I'll submit a bug report later.

Bye,
Tassilo

Thanks, one question though: does this happen with other GTK programs
running inside Xwayland?

Yes, that's what I meant (a backtrace from a crash is only interesting
on the C level).  Sorry for being unclear.

No, I've tried gedit (40.1), gimp (2.10.30), and firefox (96.0b10).
They all worked properly except firefox was light-themed although it's
usually dark-themed here.

If it helps, a build from Tuesday did not crash, the build from
yesterday's git update crashed, so you might well be able to pin it down
by bisecting
