Re: [Bug: 21.5-b26] Fatal error: assertion failed, file menubar-x.c, line 579, ABORT()

Barry> I'll save the corefile. Good! Please cd /usr1/jwandell/emacs/xemacs-21.5.26/src ;; or wherever xemacs was built gdb /usr/local/bin/xemacs core Then up 9 pobj client_data (I'm hoping it's a Lisp object.) Since I'm typing blind :-) I'm not sure that's going to work as I would hope. If it says "pobj not a valid command" or something like that, you need to find the .gdbinit file; it is built in the same directory as the xemacs binary as a normal part of the build process. use the gdb "source" command to load it. If it gives some other error, let us know and we'll try Plan B.
