XEmacs crashes (segmentation fault) with a core dump on exit/closing a frame

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 just tried XEmacs 21.4.8, the latest Gamma release, compiled it from sources, and I have a problem with it - when exiting XEmacs, or when closing a frame, in the X11 interface, it crashes with a core dump. I looked at your PROBLEMS file, and the most similar problem I found was the problem titled: *** On Solaris 2.6, XEmacs dumps core when exiting. But I am not on Solaris, it happens on remote displays as well, and according to the stack trace it does not happen during a call to XCloseDisplay. Lisp backtrace follows: #<subr delete-frame (interactive)>() # bind (command-debug-status) call-interactively(delete-frame) # (condition-case ... . error) # (catch top-level ...) Stack backtrace from GDB follows: #0 0x405735b1 in __kill () from /lib/libc.so.6 #1 0x080b5b33 in fatal_error_signal () #2 <signal handler called> #3 0x4031a292 in XtIsSubclass () from /usr/local/X11R6/lib/libXt.so.6 #4 0x4031b0f8 in XtDisplayOfObject () from /usr/local/X11R6/lib/libXt.so.6 #5 0x081af8eb in x_delete_frame () #6 0x081222d3 in delete_frame_internal () #7 0x08125786 in Fdelete_frame () #8 0x080bd41c in Ffuncall () #9 0x080952c2 in Fcall_interactively () #10 0x080bc09e in Fcommand_execute () #11 0x080fcd55 in execute_command_event () #12 0x080fd3d1 in Fdispatch_event () #13 0x0809e2fa in Fcommand_loop_1 () #14 0x0809e55d in command_loop_1 () #15 0x080c316f in condition_case_1 () #16 0x0809e6c7 in command_loop_2 () #17 0x080c303c in internal_catch () #18 0x0809e03e in initial_command_loop () #19 0x080b6b3e in xemacs_21_4_8_i686_pc_linux () #20 0x080b8e35 in main () #21 0x405604bd in __libc_start_main () from /lib/libc.so.6 It seems to me to be a bug because I compiled XEmacs 21.4.8 almost the same way (added a few options) as I compiled XEmacs 21.4.4, which works fine.
