Another crash in 21.2.33

Started XEmacs. Within the *scratch* buffer (or any other buffer) clicked on the right mouse button (button3) to display the popup menu. Dragged the mouse pointer *out of* the popup menu. -> XEmacs is locked up, still displaying the popup menu and the window manager doesn't respond to mouse clicks any more, although moving the mouse pointer around still works. Luckily I was able to switch to the terminal where I started gdb/XEmacs (with Alt-Tab under KDE) and get the following stack backtrace: (gdb) run Starting program: /usr/local/bin/xemacs Program received signal SIGSEGV, Segmentation fault. 0x80c7c50 in popup_selection_callback () (gdb) where #0 0x80c7c50 in popup_selection_callback () #1 0x80c49b9 in popup_menu_down_callback () #2 0x8196ad9 in pick_hook () #3 0x401185b0 in XtCallCallbackList () from /usr/X11R6/lib/libXt.so.6 #4 0x81935d4 in Select () #5 0x40147a4d in HandleActions () from /usr/X11R6/lib/libXt.so.6 #6 0x40147eef in HandleSimpleState () from /usr/X11R6/lib/libXt.so.6 #7 0x40148444 in _XtTranslateEvent () from /usr/X11R6/lib/libXt.so.6 #8 0x40123a74 in XtDispatchEventToWidget () from /usr/X11R6/lib/libXt.so.6 #9 0x40124428 in _XtDefaultDispatcher () from /usr/X11R6/lib/libXt.so.6 #10 0x40124689 in XtDispatchEvent () from /usr/X11R6/lib/libXt.so.6 #11 0x4012f894 in XtAppProcessEvent () from /usr/X11R6/lib/libXt.so.6 #12 0x816d919 in emacs_Xt_next_event () #13 0x80d412e in event_stream_next_event () #14 0x80d532c in next_event_internal () #15 0x80d56d8 in Fnext_event () #16 0x8092fba in Fcommand_loop_1 () #17 0x8093269 in command_loop_1 () #18 0x80b3df6 in condition_case_1 () #19 0x80933df in command_loop_2 () #20 0x80b3cbc in internal_catch () #21 0x8092cce in initial_command_loop () #22 0x80a9327 in xemacs_21_2_b33_i686_pc_linux () ---Type <return> to continue, or q <return> to quit--- #23 0x80ab04f in main () #24 0x40319a5e in __libc_start_main () at ../sysdeps/generic/libc-start.c:93 (gdb) q The program is running. Exit anyway? (y or n) y I'm beginning to wonder if there's something wrong with my environment and/or my XEmacs installation as quite a lot doesn't work with 21.2.33. So please let me know if someone else is seeing the same behaviour (I haven't had this in former betas, so I think it's a bug in 21.2.33). BTW: This is SuSE 6.4 with xf86 3.3.6. Markus
