Description of problem: Segfault in ambiguous_line_spec (C++) Version-Release number of selected component (if applicable): gdb-6.1post-1.20040607.9 How reproducible: Every time Steps to Reproduce: - compile the attached source (g++ -O0 -g -o testcase testcase.cpp) - gdb ./testcase - do 'list Test::Test' or 'break Test::Test', you will get the choice to select all or cancel. - first bug (?) the found line are shown as: '?HERE' - choose 'all' (-> '1') - on list you get a segfault, on break invalid breakpoints: "Note: breakpoint -1 (disabled) also set at pc 0x0. Breakpoint 1 at 0x0" Actual results: #0 ambiguous_line_spec (sals=0xbfffd078) at /usr/src/debug/gdb+dejagnu-20040607/gdb/cli/cli-cmds.c:997 #1 0x080b276d in list_command (arg=0x828f7b5 "Test::Test", from_tty=1) at /usr/src/debug/gdb+dejagnu-20040607/gdb/cli/cli-cmds.c:709 #2 0x080ae239 in do_cfunc (c=0x0, args=0x0, from_tty=0) at /usr/src/debug/gdb+dejagnu-20040607/gdb/cli/cli-decode.c:57 #3 0x080b012c in cmd_func (cmd=0x82c0e10, args=0x0, from_tty=0) at /usr/src/debug/gdb+dejagnu-20040607/gdb/cli/cli-decode.c:1561 #4 0x0807f665 in execute_command (p=0x828f7be "t", from_tty=1) at /usr/src/debug/gdb+dejagnu-20040607/gdb/top.c:744 #5 0x0810ab91 in command_handler (command=0x828f7b0 "list Test::Test") at /usr/src/debug/gdb+dejagnu-20040607/gdb/event-top.c:500 #6 0x0810afcb in command_line_handler (rl=0x81f9b8e "erver ") at /usr/src/debug/gdb+dejagnu-20040607/gdb/event-top.c:793 #7 0x081e0b75 in rl_callback_read_char () at /usr/src/debug/gdb+dejagnu-20040607/readline/callback.c:123 #8 0x0810a4fb in rl_callback_read_char_wrapper (client_data=0x0) at /usr/src/debug/gdb+dejagnu-20040607/gdb/event-top.c:166 #9 0x0810aa8a in stdin_event_handler (error=0, client_data=0x0) at /usr/src/debug/gdb+dejagnu-20040607/gdb/event-top.c:416 #10 0x08109d7e in handle_file_event (event_file_desc=137252424) at /usr/src/debug/gdb+dejagnu-20040607/gdb/event-loop.c:721 #11 0x08109827 in process_event () at /usr/src/debug/gdb+dejagnu-20040607/gdb/event-loop.c:334 #12 0x08109888 in gdb_do_one_event (data=0x0) at /usr/src/debug/gdb+dejagnu-20040607/gdb/event-loop.c:371 #13 0x0807f291 in do_catch_errors (uiout=0x82c1f08, data=0x0) at /usr/src/debug/gdb+dejagnu-20040607/gdb/top.c:524 #14 0x0807f110 in catcher (func=0x807f280 <do_catch_errors>, func_uiout=0x82c1f08, func_args=0xbfffd3c0, func_val=0xbfffd3b8, func_caught=0xbfffd3bc, errstring=0x0, gdberrmsg=0x0, mask=6) at /usr/src/debug/gdb+dejagnu-20040607/gdb/top.c:431 #15 0x0807f2f2 in catch_errors (func=0, func_args=0x0, errstring=0x0, mask=0) at /usr/src/debug/gdb+dejagnu-20040607/gdb/top.c:536 #16 0x080bc994 in tui_command_loop (data=0x0) at /usr/src/debug/gdb+dejagnu-20040607/gdb/tui/tui-interp.c:150 #17 0x081075f9 in current_interp_command_loop () at /usr/src/debug/gdb+dejagnu-20040607/gdb/interps.c:277 #18 0x0807a83b in captured_command_loop (data=0x0) at /usr/src/debug/gdb+dejagnu-20040607/gdb/main.c:97 Expected results: (gdb) list Test::Test [0] cancel [1] all [2] Test at testcase.cpp:27 [3] Test at testcase.cpp:27 > 1 file: "testcase.cpp", line number: 27 file: "testcase.cpp", line number: 27 (This is on FC2) Additional info: FC2 with gdb-6.0post-1.20031117.8 seems to work properly.
