Are all of the crashes you see happen because of a faulty frame font in this snippet: static void mark_frame (struct Lisp_Vector *ptr) { struct frame *f = (struct frame *) ptr; mark_vectorlike (&ptr->header); mark_face_cache (f->face_cache); #ifdef HAVE_WINDOW_SYSTEM if (FRAME_WINDOW_P (f) && FRAME_OUTPUT_DATA (f)) { struct font *font = FRAME_FONT (f); if (font && !vectorlike_marked_p (&font->header)) <<<<<<<<<<<< mark_vectorlike (&font->header); } #endif } I hope you still have this crashed session in the debugger. If so, please tell: do you have many frames in that session, or just a few (perhaps even one)? I'd like to see some more details about this frame, if possible.
