c is ?🌺 .  Are you using that character in your mode line, by any
chance?  Does it show up for you in Emacs?

Yes, I'm using the flower emoji in treemacs, related customize config is:

I'm help to tesing Emacs master branch (commit: 40eecd594ac) on Linux.

Thank you!


I compile emacs source code by:

```bash

make extraclean
./autogen.sh \
   && ./configure \
   --prefix=$(realpath ../emacs-build/$(git branch --show-current | sed
's/\//_/g'))\
   --with-imagemagick --with-xwidgets \
   --with-modules --with-x-toolkit=gtk3 --without-compress-install \
   --without-toolkit-scroll-bars --with-native-compilation --with-mailutils\
   --with-tree-sitter --with-xinput2  \
   --with-dbus  --with-native-compilation=aot \
   --with-file-notification=inotify\
   && make -j30 install
```

You might want to consider adding --enable-checking and CFLAGS="-O0 -g3
-ggdb" or equivalent to that until this bug has been found.


When I using emacs, I got crash, the backtrace is :

Do you still have the core file?

Can you print *face in this stack frame? The relevant gdb commands are
"frame 9" followed by "p *face".

c is ?🌺 .  Are you using that character in your mode line, by any
chance?  Does it show up for you in Emacs?


I believe the crash is related to the font, but I can't reproduce it. It
happens about once a day.

What would also be helpful would be to source .gdbinit from your src/
directory, (gdb:
"source/home/exec/Projects/git.savannah.gnu.org/git/emacs/src/.gdbinit"),
then "pp Vfontset_table" to see how large it is.

Thanks!
