Hi. Here is the stack trace with debugging info. It was made with the official sources from SUSE. It was compiled by adding '-g' to its '.spec' file (rpm). It was compiled with the SUSE 10.0 default tool chain. Sorry for the delay. ----------------- #0 0xffffe410 in __kernel_vsyscall () #1 0xb79cf886 in kill () from /lib/tls/libc.so.6 #2 0x080c3d7b in fatal_error_signal (sig=11) at emacs.c:3864 #3 <signal handler called> #4 byte_marker_position (marker=-1217854780) at buffer.h:674 #5 0x081b48cd in signal_syntax_table_extent_changed (extent=0x83e6aa8) at syntax.c:394 #6 0x080ef738 in extent_detach (extent=0x83e6aa8) at extents.c:1985 #7 0x080f482d in process_extents_for_deletion_mapper (extent=0xb764b7d4, arg=0xbfecdb50) at extents.c:4907 #8 0x080eff43 in map_extents (from=<value optimized out>, to=<value optimized out>, fn=0x80f47f0 <process_extents_for_deletion_mapper>, arg=0xbfecdb50, obj=141794248, after=0x0, flags=4097) at extents.c:2436 #9 0x080f05f2 in process_extents_for_deletion (object=141794248, from=<value optimized out>, to=24, destroy_them=-1218136108) at extents.c:4928 #10 0x0814287a in buffer_delete_range (buf=0x8739bc8, from=<value optimized out>, to=<value optimized out>, flags=0) at insdel.c:1483 #11 0x080a671e in Fdelete_char (count=-1, killp=-1217854780) at cmds.c:283 #12 0x080cb740 in Ffuncall (nargs=3, args=0xbfecdcb4) at eval.c:3847 #13 0x0809b01a in execute_optimized_program ( program=0x881dec8 "\n\034\212\f~~'o~$`Sf~~\024i\033~\210\viZ\023~\v\"\210~!\210)~\210\fS\211\024~~~n\t\"\210\b~\vl?~\a\212~\n\")\207", stack_depth=-1218136108, constants_data=0xb7731c00) at bytecode.c:823 #14 0x080cbab7 in Ffuncall (nargs=2, args=0xbfecddc4) at eval.c:3460 #15 0x0809b01a in execute_optimized_program ( program=0x835cdd0 "\t~\b\n~\005~~\a\b~n!!\207~\207", stack_depth=-1218136108, constants_data=0x87d76e8) at bytecode.c:823 #16 0x080cbab7 in Ffuncall (nargs=2, args=0xbfecded0) at eval.c:3460 #17 0x0809ef1b in Fcall_interactively (function=142083644, record_flag=-1217854780, keys=-1217854780) at callint.c:994 #18 0x080d00cf in Fcommand_execute (cmd=142083644, record_flag=-1218136108, keys=-1218136108) at eval.c:3114 #19 0x080dc025 in execute_command_event (command_builder=0x8644a60, event=141501164) at event-stream.c:4286 #20 0x080ddf81 in Fdispatch_event (event=141501164) at event-stream.c:4638 #21 0x080a628a in Fcommand_loop_1 () at cmdloop.c:600 #22 0x080a6349 in command_loop_1 (unused_dummy=-1217854780) at cmdloop.c:505 #23 0x080cd994 in condition_case_1 (handlers=-1218136108, bfun=0x80a6330 <command_loop_1>, barg=-1217854780, hfun=0x80a5d10 <cmd_error>, harg=-1217854780) at eval.c:1924 #24 0x080a5f0c in command_loop_2 (unused_dummy=-1217854780) at cmdloop.c:262 #25 0x080c811f in internal_catch (tag=-1218136108, func=0x80a5ed0 <command_loop_2>, arg=-1217854780, threw=0x0, thrown_tag=0x0, backtrace_before_throw=0x0) at eval.c:1530 #26 0x080a601d in initial_command_loop (load_me=-1217854780) at cmdloop.c:313 #27 0x080c5b98 in xemacs_21_5_b21_i386_suse_linux (argc=2, argv=0xbfece454, unused_envp=0x0, restart=0) at emacs.c:2754 #28 0x080c67d4 in main (argc=-1218136108, argv=0xb764b7d4, unused_envp=0xbfece460) at emacs.c:3255 -------------- No activity so far ＠ suse's bugzilla https://bugzilla.novell.com/show_bug.cgi?id=131092
