This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. Please describe as succinctly as possible: - What happened. - What you thought should have happened. - Precisely what you were doing at the time. Please also include any C or lisp back-traces that you may have. ================================================================ Dear Bug Team! I did an ediff-files, which worked fine. I quit the session, then did an ediff-buffers with some other buffers. This crashed emacs. I have done ediff-buffers successfully in the past. Lisp backtrace follows: event-window(#<motion-event 15, 8>) # bind (frame event) default-mouse-motion-handler(#<motion-event 15, 8>) # (condition-case ... . error) # (catch top-level ...) dbx trace: (dbx) where fatal_error_signal(sig = internal error: assertion failed at line 1882 in file frame.c 0), line 263 in "emacs.c" signal.pthread_kill(??, ??) at 0xd0014c44 signal._p_raise(??) at 0xd001410c raise.raise(??) at 0xd017510c abort() at 0xd016e860 assert_failed(file = (nil), line = -1, expr = warning: Unable to access address 0xfffff fff from core (invalid char ptr (0xffffffff))), line 2617 in "emacs.c" start_end_of_last_line(??, ??, ??), line 6619 in "redisplay.c" pixel_to_glyph_translation(??, ??, ??, ??, ??, ??, ??, ??), line 6693 in "redisplay.c" event_pixel_translation(??, ??, ??, ??, ??, ??, ??, ??), line 1704 in "events.c" Fevent_window(??), line 1838 in "events.c" unnamed block $b1787, line 3197 in "eval.c" funcall_recording_as(??, ??, ??), line 3197 in "eval.c" Ffuncall(??, ??), line 3238 in "eval.c" Fbyte_code(??, ??, ??), line 416 in "bytecode.c" unnamed block $b1832, line 3597 in "eval.c" funcall_lambda(??, ??, ??), line 3597 in "eval.c" unnamed block $b1800, line 3214 in "eval.c" funcall_recording_as(??, ??, ??), line 3214 in "eval.c" call1(??, ??), line 3238 in "eval.c" execute_internal_event(??), line 2953 in "event-stream.c" Fdispatch_event(??), line 4690 in "event-stream.c" Fcommand_loop_1(), line 579 in "cmdloop.c" command_loop_1(??), line 494 in "cmdloop.c" condition_case_1(??, ??, ??, ??, ??), line 1653 in "eval.c" unnamed block $b1011, line 256 in "cmdloop.c" unnamed block $b1010, line 256 in "cmdloop.c" command_loop_2(??), line 256 in "cmdloop.c" internal_catch(??, ??, ??, ??), line 1328 in "eval.c" initial_command_loop(??), line 305 in "cmdloop.c" xemacs_21_1_p3_rs6000_ibm_aix4_3_0_0(argc = internal error: assertion failed at line 18 82 in file frame.c 537804372, argv = internal error: assertion failed at line 1882 in file frame.c 0x200e3908, envp = 0xffffffff, restart = internal error: assertion failed at line 1882 in file frame.c 804394296), line 1714 in "emacs.c" main(argc = internal error: assertion failed at line 1882 in file frame.c 1, argv = internal error: assertion failed at line 1882 in file frame.c 0xa012b004, envp = internal error: assertion failed at line 1882 in file frame.c 0x2ff21ac0), line 2131 in "emacs.c" (dbx) ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: AIX thermes 3 4 002018694600 ./configure 'rs6000-ibm-aix4.3.0.0' '--prefix=/usr/local' '--bindir=/usr/local/bin/rs6000-ibm-aix4.3.0.0' '--site-includes=/afs/informatik.uni-tuebingen.de/home/sperber/build/compface /afs/informatik.uni-tuebingen.de/rs_aix41/include' '--site-libraries=/afs/informatik.uni-tuebingen.de/home/sperber/build/compface /afs/informatik.uni-tuebingen.de/rs_aix41/lib' '--with-menubars=lucid' '--with-scrollbars=lucid' '--with-xpm' '--with-xface' '--with-jpeg' '--with-png' '--with-database=dbm' XEmacs 21.1-p3 "Acadia" configured for `rs6000-ibm-aix4.3.0.0'.
