[CRASH] gnuclient vs display-time

In XEmacs 21.2 (beta37) "Pan" [Lucid] (i686-pc-linux) of Mon Jan 8 2001 on wibble configured using `configure --pdump --rel-alloc --with-sound=none' (This is actually cvs from ~18:00 GMT Jan 9. I had to go run watch the eclipse). Please describe exactly what actions triggered the bug and the precise symptoms of the bug: xemacs -q -l gnuclient-crash.el crashes 100% reproducibly at the first garbage collection after I connect using gnuclient -nw ellcc.c (backtrace at end, I have this puppy in gdb). gnuclient-crash.el: --begin-- (display-time) (gnuserv-start) --end-- Important (maybe) datapoints: If I run display-time using M-x display-time this doesn't happen. If I run display-time from the gnuclient frame after connecting this doesn't happen. The crash is at alloc.c:3035, 3034 string = from_s_chars->string; 3035 assert (!(FREE_STRUCT_P (string))); (gdb) p from_s_chars->string $5 = (Lisp_String *) 0x656d6f68 (gdb) p *(from_s_chars->string) Cannot access memory at address 0x656d6f68 (gdb) p from_s_chars $6 = (struct string_chars *) 0x8549208 (gdb) p *from_s_chars $7 = { string = 0x656d6f68, chars = "/" } from_s_chars->string is _always_ 0x656d6f68 from_s_chars->chars is _always_ "/" Backtrace: #0 compact_string_chars () at alloc.c:3035 #1 0x8083fe7 in gc_sweep () at alloc.c:3184 #2 0x808468b in garbage_collect_1 () at alloc.c:3504 #3 0x808489e in Fgarbage_collect () at alloc.c:3594 #4 0x80bda26 in Ffuncall (nargs=1, args=0xbfffed98) at eval.c:3528 #5 0x80951e0 in Fcall_interactively (function=1078273200, record_flag=1078355520, keys=1078356624) at callint.c:528 #6 0x80bc20d in Fcommand_execute (cmd=1078273200, record_flag=1078355520, keys=1078356624) at eval.c:2970 #7 0x80bda5d in Ffuncall (nargs=3, args=0xbfffef28) at eval.c:3528 #8 0x809172e in execute_optimized_program (program=0x8590408 "\b\030Á\bÂa«\004ê$\bÄk«\004Ū\034\b¨«\aÆÇ\b\"ª\022\b:«\r\b＠¨«\bÆÇ\b＠\"ª\002È!\026\t)\016\n«Ut«RË\016\t!\016\t\036\f\036\rÎ\016\tÏ\"\210\016\r­<\016\020¬\023Ñ Ò a«\aÓ pa«\006Ô \210ª\004Õ \210Ö×!­\036ØÙÆ\016\rA«\004Úª\002Û\016\fÜ\016\r!#\"\210Ö\016\035!\210ÞÙ!*\207Î\016\tÏ\"\207", stack_depth=7, constants_data=0x404f81f4) at bytecode.c:746 #9 0x8091343 in funcall_compiled_function (fun=1079129196, nargs=1, args=0xbffff088) at bytecode.c:518 #10 0x80bdbe7 in Ffuncall (nargs=2, args=0xbffff084) at eval.c:3563 #11 0x80967bf in Fcall_interactively (function=1078243704, record_flag=1078356624, keys=1078356624) at callint.c:940 #12 0x80bc20d in Fcommand_execute (cmd=1078243704, record_flag=1078356624, keys=1078356624) at eval.c:2970 #13 0x80f72a5 in execute_command_event (command_builder=0x8469b80, event=140048968) at event-stream.c:3833 #14 0x80f7f0c in Fdispatch_event (event=139216760) at event-stream.c:4164 #15 0x809caf2 in Fcommand_loop_1 () at cmdloop.c:583 #16 0x809cd92 in command_loop_1 (dummy=1078356624) at cmdloop.c:494 #17 0x80c3c83 in condition_case_1 (handlers=1078356264, bfun=0x809cd54 <command_loop_1>, barg=1078356624, hfun=0x809ce04 <cmd_error>, harg=1078356624) at eval.c:1651 #18 0x809cef7 in command_loop_2 (dummy=1078356624) at cmdloop.c:256 #19 0x80c3b4c in internal_catch (tag=1078184832, func=0x809cebc <command_loop_2>, arg=1078356624, threw=0x0) at eval.c:1317 #20 0x809c366 in initial_command_loop (load_me=1078356624) at cmdloop.c:305 #21 0x80b589d in xemacs_21_2_b37_i686_pc_linux () at emacs.c:2253 #22 0x80b773b in main (argc=4, argv=0xbffff6a4, envp=0xbffff6b8) at emacs.c:2620 #23 0x40303e6c in __libc_start_main () from /lib/libc.so.6 Recent keystrokes: m x e m a c s - b f6 e f6 C-n [ C R A S H ] SPC C-u ESC x e e m a BS BS BS m a TAB c TAB BS v TAB RET C-a C-f C-f C-f C-f C-f C-f C-f C-f C-f C-f C-f C-f C-f C-f C-f C-f C-f g n u c l i e n t SPC & SPC d i s p l a y - t i m e C-k C-n C-n C-n C-n C-n ESC x r e TAB p o TAB r t TAB RET Recent messages (most recent first): Loading emacsbug...done Loading emacsbug...
