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 frequently have open two VM Inboxes for different mailing lists. They access separately IMAP Inboxes at the server end, but are set to retrieve email only on demand. This assert happens with some regularity if I have both Inboxes open. It is much less likely to occur with only one. Sometimes the failure occurs spontaneously and at others like this it happens when I click on the frame with one of these Inboxes. I have Lisp and stack traces from two occurences. The stack traces are hand assembled - I'm can't seem to get a usable core file from Cygwin First example ============= Lisp backtrace follows: next-event(#<buttonup-event button1up>) # (unwind-protect ...) # bind (mouse-down xthresh ythresh orig-x orig-y buffer mouse-grabbed-buffer mouse-moved overriding-hooks event) mouse-track(#<buttonup-event button1up>) # bind (command-debug-status) call-interactively(mouse-track) # (condition-case ... . error) # (catch top-level ...) Stack trace: 0x043130b fatal_error_signal emacs.c:539 [Cygwin stuff] 0x04357C9 assert_failed emacs.c:3321 0x04852F0 pop_low_level_timeout event-stream.c:1037 0x05106C6 check_what_happened signal.c:115 0x043A30D Ffuncall eval.c:3474 0x043FA33 call4 eval.c:4235 0x04E5696 clear_echo_area minibuf.c:686 0x048058B Fnext_event event-stream.c:707 0x043A55C Ffuncall eval.c:3528 Second example ============== Lisp backtrace follows: # (condition-case ... . error) # (catch top-level ...) Stack trace: 0x043130b fatal_error_signal emacs.c:539 [Cygwin stuff] 0x04357C9 assert_failed emacs.c:3321 0x04852F0 pop_low_level_timeout event-stream.c:1037 0x05106C6 check_what_happened signal.c:115 0x04A50CA internal_equal fns.c:2649 0x04F9A24 redisplay_frame redisplay.c:6478 0x04F9CF6 redisplay_device redisplay.c:6663 0x04F9F17 redisplay_without_hooks redisplay.c:6751 0x04FF64E redisplay redisplay.c:6806 0x04ED57F status_notify process.c:1507 0x0480504 Fnext_event event-stream.c:2194 ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: CYGWIN_NT-5.0 DBUSH1-MOBL 1.3.12(0.54/3/2) 2002-07-03 16:42 i686 unknown ./configure XEmacs 21.4.8 "Honest Recruiter (Windows [3])" configured for `i686-pc-cygwin'.
