Here is another shot at the syntax highlighting crash problem. Once again, I launched XEmacs as "xemacs emacs.c" (in the XEmacs source tree), selected Options -> Syntax Highlighting -> In This Buffer, and then selected it again immediately. Then boom. The C backtrace still has the "??" bits; as you can see I ran ./configure with "--debug" and "--error-checking=all". When I strip the binary, it gets smaller by a factor of about 3.5, so the binary was definitely not stripped when the crash happened. Something else weird must be happening, but I have no clue. === Fatal error: assertion failed, file gui-x.c, line 274, RECORD_TYPEP (obj, lrecord_type_cons) Fatal error (6). === Lisp backtrace: === # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # bind (inhibit-quit) # (condition-case ... . error) # (catch top-level ...) === C backtrace: === warning: core file may not match specified executable file. #0 0x7001a6fc in kill () (gdb) where #0 0x7001a6fc in kill () #1 0x00051b84 in fatal_error_signal (sig=6) at emacs.c:3440 #2 <signal handler called> #3 0x7001a6fc in kill () #4 0x7006f984 in abort () #5 0x00052ecc in print_subr (obj=16046084, printcharfun=16046084, escapeflag=1) at emacs.c:4283 #6 0x00051b84 in fatal_error_signal (sig=15139776) at emacs.c:3440 #7 0x001de868 in popup_selection_callback (widget=0xe9b7c0, ignored_id=0, client_data=0xf4d804) at lisp.h:1615 #8 0x001fe6e0 in pick_hook (w=0xe9b7c0, client_data=0xe9b650, call_data=0xe98550) at lwlib-Xlw.c:110 #9 0x00941b14 in ??

Warning: XEmacs: Mod1 is being used for both Mode_switch and Alt. Warning: Two distinct modifier keys (such as Meta and Hyper) cannot generate the same modifier bit, because Emacs won't be able to tell which modifier was actually held down when some other key is pressed. It won't be able to tell Meta-x and Hyper-x apart, for example. Change one of these keys to use some other modifier bit. If you intend for these keys to have the same behavior, then change them to have the same keysym as well as the same modifier bit. Warning: The meanings of the modifier bits Mod1 through Mod5 are determined by the keysyms used to control those bits. Mod1 does NOT always mean Meta, although some non-ICCCM-compliant programs assume that. Loading cus-face...done Loading cus-face... -- Chris music is what numbers feel like San Francisco, CA
