After recent build, emacs is crashing frequently when using tree-sitter modes. The following backtrace was generated after opening a few C files, enabling c-ts-mode, and moving the cursor around a bit. I dont have precise steps for repeatability at this point (sorry!), as it seems to occur during garbage collection. Let me know if there is more useful output I could provide. $ emacs -Q Fatal error 11: Segmentation fault Backtrace: emacs(emacs_backtrace+0x47)[0x5f9bb9f83338] emacs(terminate_due_to_signal+0x8f)[0x5f9bb9f5fb40] emacs(+0x1dc391)[0x5f9bb9f81391] emacs(+0x1dc3f6)[0x5f9bb9f813f6] emacs(+0x1dc423)[0x5f9bb9f81423] /lib/x86_64-linux-gnu/libc.so.6(+0x42520)[0x71c8fe442520] /usr/local/lib/libtree-sitter.so.0(ts_query_cursor_delete+0x11)[0x71c902abf2c1] emacs(treesit_delete_query+0x1a)[0x5f9bba078994] emacs(+0x221b29)[0x5f9bb9fc6b29] emacs(garbage_collect+0x705)[0x5f9bb9fcb1a2] emacs(maybe_garbage_collect+0x2a)[0x5f9bb9fcb3c9] emacs(Ffuncall+0x171)[0x5f9bb9feac4d] emacs(internal_condition_case_n+0x7d)[0x5f9bb9fe9713] emacs(+0xb1ec4)[0x5f9bb9e56ec4] emacs(+0xb1f9d)[0x5f9bb9e56f9d] emacs(+0xe2468)[0x5f9bb9e87468] emacs(+0xe265e)[0x5f9bb9e8765e] emacs(+0xe2517)[0x5f9bb9e87517] emacs(+0xe265e)[0x5f9bb9e8765e] emacs(+0xe3732)[0x5f9bb9e88732] emacs(+0xe59b4)[0x5f9bb9e8a9b4] emacs(+0xfb9d5)[0x5f9bb9ea09d5] emacs(+0xfcfa6)[0x5f9bb9ea1fa6] emacs(internal_condition_case_1+0x68)[0x5f9bb9fe95f8] emacs(+0xe77ad)[0x5f9bb9e8c7ad] emacs(redisplay+0xd)[0x5f9bb9e8cd39] emacs(read_char+0x714)[0x5f9bb9f71d34] emacs(+0x1cf6ff)[0x5f9bb9f746ff] emacs(+0x1d21d3)[0x5f9bb9f771d3] emacs(internal_condition_case+0x5f)[0x5f9bb9fe957a] emacs(command_loop_2+0x27)[0x5f9bb9f627ef] emacs(internal_catch+0x3e)[0x5f9bb9fe94ac] emacs(+0x1bd7a5)[0x5f9bb9f627a5] emacs(recursive_edit_1+0x69)[0x5f9bb9f67206] emacs(Frecursive_edit+0xbf)[0x5f9bb9f6756d] emacs(main+0x1f85)[0x5f9bb9f61b1d] /lib/x86_64-linux-gnu/libc.so.6(+0x29d90)[0x71c8fe429d90] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0x80)[0x71c8fe429e40] emacs(_start+0x25)[0x5f9bb9e3d9c5] Segmentation fault In GNU Emacs 31.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.33, cairo version 1.16.0) of 2024-07-21 built on noah-X580VD Repository revision: ccb856189f483abfaa584f428b09a863f816a040 Repository branch: master Windowing system distributor 'The X.Org Foundation', version 11.0.12101004 System Description: Ubuntu 22.04.4 LTS Configured using: 'configure --prefix=/usr/local --with-modules --with-tree-sitter --with-threads --with-x-toolkit=gtk3 --with-xwidgets --with-gnutls --with-mailutils --with-jpeg --with-png --with-rsvg --with-tiff --with-xml2 --with-xpm --with-imagemagick CC=gcc-12 CXX=gcc-12 CFLAGS=-ggdb3 CXXFLAGS=' Configured features: CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ IMAGEMAGICK JPEG LCMS2 LIBSELINUX LIBXML2 MODULES NATIVE_COMP NOTIFY INOTIFY PDUMPER PNG RSVG SECCOMP SOUND SQLITE3 THREADS TIFF TOOLKIT_SCROLL_BARS TREE_SITTER WEBP X11 XDBE XIM XINPUT2 XPM XWIDGETS GTK3 ZLIB Important settings: value of $LANG: en_US.UTF-8 value of $XMODIFIERS: @im=ibus locale-coding-system: utf-8-unix Major mode: Lisp Interaction Minor modes in effect: tooltip-mode: t global-eldoc-mode: t eldoc-mode: t show-paren-mode: t electric-indent-mode: t mouse-wheel-mode: t tool-bar-mode: t menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t minibuffer-regexp-mode: t line-number-mode: t indent-tabs-mode: t transient-mark-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t Load-path shadows: None found.
