At the end of the bug report there is info on how this instance of Emacs was configured for building. Isn't Configured using: 'configure -C --prefix=/usr/local/stow/emacs-snapshot [...] --enable-checking=yes,glyphs --enable-check-lisp-object-type --with-native-compilation 'CFLAGS=-g3 -O0 [...] the right result? Should I disable native compilation? > The output of (mouse-generate-font-menu) run on your system would also > be helpful. Sure. I learned about the C-0 prefix key for C-x C-e to show unabbreviated output. I also learned about so-long-mode, but this line is too long. I therefore attach the output as a xz compressed file, because displaying it in Emacs bogs Emacs down. Ciao; Gregor -- -... --- .-. . -.. ..--.. ...-.-
