Hello, I'm help to tesing Emacs master branch (commit: 40eecd594ac) on Linux. 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 ``` When I using emacs, I got crash, the backtrace is : ``` line to your configuration file "/home/exec/.config/gdb/gdbinit".

font, but I can't reproduce it. It happens about once a day. What information should I provide to help investigate this bug? And my OS info is: ``` ❯ nix-info -m - system: `"x86_64-linux"` - host os: `Linux 6.6.45, NixOS, 24.05 (Uakari), 24.05.20240813.4a92571` - multi-user?: `yes` - sandbox: `yes` - version: `nix-env (Nix) 2.18.5` - channels(exec): `""` - channels(root): `""` - nixpkgs: `/nix/store/qszplw617r895nbcprgyj139c9a3r0xs-source` ``` Thank you!
