Create a directory, a file and a shortcut in the file system: cd mkdir -p path/to/long/directory/in/file/system echo "hello" > path/to/long/directory/in/file/system/file ln -s path/to/long/directory/in/file/system/ shortcut In emacs C-x C-f shortcut M-x grep hello * in the output mouse-1 on file 1:hello Then type: C-x C-b Then you see that the filename of the file found in the grep output is ~/path/to/long/directory/in/file/system/file not ~/shortcut/file as you would have expected, and how it was before in emacs version 27.1. Same thing happens in emacs 29.4. I fixed this bug by removing two calls to file-truename in the function compilation-find-file-1 and one call to the same function in compilation-find-file (both functions in lisp/progmodes/compile.el) Configured using:  'configure --prefix=/opt/emacs' Configured features: CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GSETTINGS HARFBUZZ JPEG LIBSELINUX MODULES NOTIFY INOTIFY PDUMPER PNG SECCOMP SOUND THREADS TIFF TOOLKIT_SCROLL_BARS X11 XDBE XIM XINPUT2 XPM GTK3 ZLIB Important settings:   value of $LC_MONETARY: sv_SE.UTF-8   value of $LC_NUMERIC: sv_SE.UTF-8   value of $LANG: en_US.UTF-8   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   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.
