================================================================ Dear Bug Team! I've been editing some XSLT stylesheet and tried to set selective display (with C-u 20 C-x $). xemacs crashed with assertion failure: ================================================================ Fatal error: assertion failed, file buffer.h, line 617, (x) >= ((Charbpos) 1) && x <= ((buf)->text->bufz + 0) Fatal error (6). Your files have been auto-saved. Use `M-x recover-session' to recover them. Your version of XEmacs was distributed with a PROBLEMS file that may describe your crash, and with luck a workaround. Please check it first, but do report the crash anyway. Please report this bug by invoking M-x report-emacs-bug, or by selecting `Send Bug Report' from the Help menu. If that won't work, send ordinary email to `crashes(a)xemacs.org&#39;. *MAKE SURE* to include this entire output from this crash, especially including the Lisp backtrace, as well as the XEmacs configuration from M-x describe-installation (or equivalently, the file `Installation' in the top of the build tree). *Please* try *hard* to obtain a C stack backtrace; without it, we are unlikely to be able to analyze the problem. Locate the core file produced as a result of this crash (often called `core' or `core.<process-id>', and located in the directory in which you started XEmacs or your home directory), and type gdb /usr/local/bin/xemacs core then type `where' at the debugger prompt. No GDB on your system? You may have DBX, or XDB, or SDB. (Ask your system administrator if you need help.) If no core file was produced, enable them (often with `ulimit -c unlimited') in case of future recurrance of the crash. Lisp backtrace follows: # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) center-to-window-line(35 nil) # bind (window n) recenter(35) # bind (current-vpos arg) set-selective-display(20) # bind (command-debug-status) call-interactively(set-selective-display) (dispatch-event "[internal]") # (condition-case ... . error) # (catch top-level ...) ================================================================ No core was produced, so I run `ulimit -c unlimited' and tried to reproduce the error, which wasn't difficult (it does depend on the prefix parameter to set-selective-display, but I don't know whether it's specific to the XSLT stylesheet; I can send the stylesheet if you want it). This time I got a core, from which gdb shows the following backtrace: ================================================================ #0 0x4059cdf1 in kill () from /lib/libc.so.6 #1 0x080f8daf in fatal_error_signal (sig=6) at emacs.c:3513 #2 <signal handler called> #3 0x4059cdf1 in kill () from /lib/libc.so.6 #4 0x4059cbd8 in raise () from /lib/libc.so.6 #5 0x4059e4d9 in abort () from /lib/libc.so.6 #6 0x080f88db in really_abort () at emacs.c:4363 #7 0x080f783a in assert_failed (file=0x8366412 "buffer.h", line=6, expr=0xbfffe064 " ") at emacs.c:3699 #8 0x08254d56 in create_text_block (w=0x8564108, dl=0x888b690, byte_start_pos=8658, prop=0xbfffe79c, type=0) at buffer.h:617 #9 0x082766a9 in generate_display_line (w=0x8564108, dl=0x888b690, bounds=1, start_pos=8649, prop=0xbfffe79c, type=2) at buffer.h:615 #10 0x0827345d in regenerate_window (w=0x8564108, start_pos=8649, point=0, type=2) at redisplay.c:5638 #11 0x082615e3 in update_line_start_cache (w=0x8564108, from=5824, to=7792, point=5824, no_regen=0) at redisplay.c:8625 #12 0x082603bd in point_in_line_start_cache (w=0x8564108, point=5824, min_past=12) at redisplay.c:7932 #13 0x08260c5e in start_with_point_on_display_line (w=0x8564108, point=5824, line=12) at redisplay.c:8388 #14 0x08340bb5 in Fcenter_to_window_line (n=12, window=5824) at lisp.h:2460 #15 0x080fe788 in Ffuncall (nargs=3, args=0x19) at eval.c:3843 #16 0x080a8052 in execute_optimized_program ( program=0x8885c68 "Â\t:?­\002\t\b\"\210\t?­\aÃÄ\b!Å\"\207", stack_depth=8, constants_data=0x407a346c) at bytecode.c:609 #17 0x08106023 in funcall_compiled_function (fun=1082304008, nargs=1, args=0xbfffebe8) at opaque.h:36 #18 0x080fe6cc in Ffuncall (nargs=2, args=0xbfffebe4) at eval.c:3881 #19 0x080a8052 in execute_optimized_program ( program=0x8839610 "\nÃa«\005ÄÅ!\210\214e`}\210Æ b\210ÇÈ !)\031\b­\004É\b!\022Ê\t!\210)ËÌ ÆÌ !\"\210ÍÎÃ\"\210Ï\nÃ\"\210ÍÐÃ\"\207!", stack_depth=4, constants_data=0x40789ad8) at bytecode.c:609 #20 0x08106023 in funcall_compiled_function (fun=1082239240, nargs=1, args=0xbfffed54) at opaque.h:36 #21 0x080fe6cc in Ffuncall (nargs=2, args=0xbfffed50) at eval.c:3881 #22 0x080ad793 in Fcall_interactively (function=1080856608, record_flag=1081004592, keys=1081004592) at callint.c:995 #23 0x080fcca1 in Fcommand_execute (cmd=1080856608, record_flag=1081004592, keys=1081004592) at eval.c:3106 #24 0x0811d0b2 in execute_command_event (command_builder=0x860ac50, event=142826080) at event-stream.c:4209 #25 0x081173a2 in Fdispatch_event (event=142826080) at event-stream.c:4561 #26 0x080c06a8 in Fcommand_loop_1 () at cmdloop.c:573 #27 0x080fb47d in condition_case_1 (handlers=1081002504, bfun=0x80c0c60 <command_loop_1>, barg=1081004592, #28 0x080c0ea4 in command_loop_2 (dummy=1081004592) at cmdloop.c:252 #29 0x080fb32a in internal_catch (tag=0, func=0x80c0e50 <command_loop_2>, arg=1081004592, threw=0x0, thrown_tag=0x0) at eval.c:1527 #30 0x080c09bf in initial_command_loop (load_me=0) at cmdloop.c:301 #31 0x080f6a9d in xemacs_21_5_b15_i686_pc_linux (argc=2, argv=0xbffff464, envp=0xbffff470, restart=0) at emacs.c:2373 #32 0x080f75f2 in main () at emacs.c:2865 #33 0x4058b4a2 in __libc_start_main () from /lib/libc.so.6 ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux linux 2.4.19-4GB #1 Wed Sep 25 18:58:10 UTC 2002 i686 unknown ./configure '--with-mule' XEmacs 21.5-b15 "celery" (+CVS-20030905) configured for `i686-pc-linux'.
