Description of problem: Since installing bash-4.0-1.fc11.x86_64, each time I ask bash to "complete", it segfaults. Here is a typical crash: Core was generated by `bash'. Program terminated with signal 11, Segmentation fault. #0 restore_token_state () at ./parse.y:1631 1631 last_read_token = ts[0]; (gdb) where #0 restore_token_state () at ./parse.y:1631 #1 restore_parser_state (ps=0x7fffe29a6dd0) at ./parse.y:5560 #2 0x0000000000463f80 in gen_shell_function_matches ( cw=<value optimized out>, nw=<value optimized out>, lwords=<value optimized out>, ind=<value optimized out>, line=<value optimized out>, text=<value optimized out>, cs=<value optimized out>) at pcomplete.c:1043 #3 gen_compspec_completions (cs=0x114c9d0, cmd=<value optimized out>, word=<value optimized out>, start=0, end=<value optimized out>) at pcomplete.c:1286 #4 0x00000000004647a2 in programmable_completions (cmd=0x114c9b0 "cd", word=0x114c990 "str", start=0, end=<value optimized out>, foundp=<value optimized out>) at pcomplete.c:1444 #5 0x000000000045d03a in attempt_shell_completion (text=0x114c990 "str", start=3, end=6) at bashline.c:1334 #6 0x00000000004859ff in gen_completion_matches (text=0x114c990 "str", start=0, end=-48, our_func=0x484590 <rl_filename_completion_function>, found_quote=18253648, quote_char=97) at complete.c:1023 #7 0x0000000000486e88 in rl_complete_internal (what_to_do=9) at complete.c:1746 #8 0x000000000047eec3 in _rl_dispatch_subseq (key=9, map=0x6d0da0, got_subseq=0) at readline.c:820 #9 0x000000000047f627 in readline_internal_char () at readline.c:599 ---Type <return> to continue, or q <return> to quit--- #10 0x000000000047fa45 in readline_internal_charloop () at readline.c:626 #11 readline_internal () at readline.c:640 #12 e (prompt=<value optimized out>) at readline.c:384 #13 0x000000000041e55d in yy_readline_get () at ./parse.y:1314 #14 0x000000000041f6e6 in yy_getc () at ./parse.y:1247 #15 shell_getc (remove_quoted_newline=1) at ./parse.y:2094 #16 0x0000000000421cea in read_token (command=<value optimized out>, command=<value optimized out>) at ./parse.y:2727 #17 0x0000000000424ade in yylex () at ./parse.y:2360 #18 yyparse () at y.tab.c:2010 #19 0x000000000041d09a in parse_command () at eval.c:229 #20 0x000000000041d166 in read_command () at eval.c:273 #21 0x000000000041d3c8 in reader_loop () at eval.c:138 #22 0x000000000041caaf in main (argc=0, argv=<value optimized out>, env=<value optimized out>) at shell.c:751 (gdb) [tbl@tlondon ~]$ Version-Release number of selected component (if applicable): ash-completion-20080705-3.20090211git47d0c5b.noarch bash-4.0-1.fc11.x86_64 bash-debuginfo-4.0-1.fc11.x86_64 How reproducible: Every time Steps to Reproduce: 1.
