Freeze 21.2.b32: X Error of failed request: BadWindow (invalid Window parameter)

Hi, after the text image fix, here is a new bug report :-) XEmacs version as of today (emacs-version) "XEmacs 21.2 (beta32) \"Kastor & Polydeukes\" [Lucid] (sparc-sun-solaris2.6, Mule) of Tue Apr 11 2000 on inss24" system-configuration-options "--prefix=/usr/users/kaage/lib/xemacs --dynamic=yes --with-dialogs=athena --with-site-lisp --with-mule" Originally, I wanted to trace down a SEGFAULT being produced while heavily using gnuclient. Unfortunately, this bug was not reproducible with a vanilla XEmacs. Instead, a freeze occurred. I've started xemacs -vanilla. After starting gnuserv, I've loaded an html file via gnuclient. Now, repeated quitting of the file via C-x # and loading again with gnuclient after about 20 cycles yields to a freeze of XEmacs including the following X error: xemacs: X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 8 (X_MapWindow) Resource id in failed request: 0x2c001d3 Serial number of failed request: 15906 Current serial number in output stream: 15916 Attaching with GDB shows where XEmacs is frozen: Attaching to program `/usr/users/kaage/lib/xemacs/bin/xemacs-21.2-b32', process 15292 Symbols already loaded for /lib/libXm.so.3 Symbols already loaded for /lib/libXaw.so.5 Symbols already loaded for /usr/openwin/lib/libtiff.so Symbols already loaded for /tools/misc/lib/libpng.so.2 Symbols already loaded for /tools/misc/lib/libjpeg.so.62 Symbols already loaded for /usr/openwin/lib/libtt.so.2 Symbols already loaded for /lib/libXmu.so.4 Symbols already loaded for /lib/libXt.so.4 Symbols already loaded for /lib/libXext.so.0 Symbols already loaded for /lib/libX11.so.4 Symbols already loaded for /lib/libdl.so.1 Symbols already loaded for /lib/libkstat.so.1 Symbols already loaded for /lib/libm.so.1 Symbols already loaded for /lib/libsocket.so.1 Symbols already loaded for /lib/libnsl.so.1 Symbols already loaded for /lib/libc.so.1 Symbols already loaded for /tools/misc/lib/libz.so.1.1.3 Symbols already loaded for /lib/libSM.so.6 Symbols already loaded for /lib/libICE.so.6 Symbols already loaded for /lib/libmp.so.2 Symbols already loaded for /lib/libXm.so.3 Symbols already loaded for /lib/libXaw.so.5 Symbols already loaded for /usr/openwin/lib/libtiff.so Symbols already loaded for /tools/misc/lib/libpng.so.2 Symbols already loaded for /tools/misc/lib/libjpeg.so.62 Symbols already loaded for /usr/openwin/lib/libtt.so.2 Symbols already loaded for /lib/libXmu.so.4 Symbols already loaded for /lib/libXt.so.4 Symbols already loaded for /lib/libXext.so.0 Symbols already loaded for /lib/libX11.so.4 Symbols already loaded for /lib/libdl.so.1 Symbols already loaded for /lib/libkstat.so.1 Symbols already loaded for /lib/libm.so.1 Symbols already loaded for /lib/libsocket.so.1 Symbols already loaded for /lib/libnsl.so.1 Symbols already loaded for /lib/libc.so.1 Symbols already loaded for /tools/misc/lib/libz.so.1.1.3 Symbols already loaded for /lib/libSM.so.6 Symbols already loaded for /lib/libICE.so.6 Symbols already loaded for /lib/libmp.so.2 0xef0b7318 in poll () from /lib/libc.so.1 (gdb) where #0 0xef0b7318 in poll () from /lib/libc.so.1 #1 0xef0ccb24 in select () from /lib/libc.so.1 #2 0xef2cdf94 in _XWaitForReadable () from /lib/libX11.so.4 #3 0xef28f3d8 in _XRead () from /lib/libX11.so.4 #4 0xef2918ec in _XReply () from /lib/libX11.so.4 #5 0xef2a51bc in XQueryColor () from /lib/libX11.so.4 #6 0x20757c in x_generate_shadow_pixels (f=0x65c800, top_shadow=0xefffe524, bottom_shadow=0xefffe520, background=15066597, core_background=15066597) at redisplay-x.c:1609 #7 0x20450c in x_bevel_area (w=0x85f800, findex=1, x=4, y=584, width=735, height=18, shadow_thickness=2, edges=15, style=EDGE_BEVEL_OUT) at redisplay-x.c:549 #8 0x1b1eb8 in bevel_modeline (w=0x85f800, dl=0x803000) at redisplay-output.c:2344 #9 0x204254 in x_output_display_block (w=0x85f800, dl=0x803000, block=0, start=1, end=82, start_pixpos=4, cursor_start=0, cursor_width=0, cursor_height=0) at redisplay-x.c:507 #10 0x1ae398 in redisplay_output_display_block (w=0x85f800, dl=0x803000, block=0, start=1, end=82, start_pixpos=0, cursor_start=0, cursor_width=0, cursor_height=0) at redisplay-output.c:1134 #11 0x1acf9c in output_display_line (w=0x85f800, cdla=0x6f0340, ddla=0x6f0940, line=0, force_start=4, force_end=739) at redisplay-output.c:650 #12 0x1b18d4 in redisplay_output_window (w=0x85f800) at redisplay-output.c:2256 ---Type <return> to continue, or q <return> to quit--- #13 0x1a1ae4 in redisplay_window (window=8779776, skip_selected=1) at redisplay.c:6243 #14 0x1a2148 in redisplay_frame (f=0x82a400, preemption_check=0) at redisplay.c:6455 #15 0x1a23b4 in redisplay_device (d=0x658d00, automatic=8561664) at redisplay.c:6533 #16 0x1a2934 in redisplay_without_hooks () at redisplay.c:6622 #17 0x1a2bb4 in redisplay () at redisplay.c:6679 #18 0xfc588 in Fnext_event (event=6709948, prompt=3131396) at event-stream.c:2180 #19 0x88444 in Fcommand_loop_1 () at cmdloop.c:566 #20 0x88194 in command_loop_1 (dummy=3131396) at cmdloop.c:490 #21 0xa9ff4 in condition_case_1 (handlers=3131492, bfun=0x88148 <command_loop_1>, barg=3131396, hfun=0x875f8 <cmd_error>, harg=3131396) at eval.c:1644 #22 0x8770c in command_loop_3 () at cmdloop.c:252 #23 0x8772c in command_loop_2 (dummy=3131396) at cmdloop.c:263 #24 0xa9adc in internal_catch (tag=3213556, func=0x87720 <command_loop_2>, arg=3131396, threw=0x0) at eval.c:1310 #25 0x87a90 in initial_command_loop (load_me=554784) at cmdloop.c:301 #26 0xa52ac in sort_args (argc=2921472, argv=0xeffff0f4) at emacs.c:1873 (gdb) Cheers, Uli
