>Environment:
Linux 2.4.21-199-athlon (SuSE 9.0)
glibc 2.3.2
GDB 6.0 (self-compiled)
>Description:
If I set a breakpoint, debug the program, finish it, recompile it (without changes!) and start it again, do some steps, gdb segfaults.

Backtrace is attached and should show the problem.
>How-To-Repeat:
[~] $ gdb test
GNU gdb 6.0
[...]
(gdb) break main
Breakpoint 1 at 0x804834c: file test.c, line 7.
(gdb) run
(gdb) s
(gdb) s
(gdb) s
(gdb) c
[touch test.c]
(gdb) make
(gdb) run
`/home/bwalle/test' has changed; re-reading symbols.
Breakpoint 1, main () at test.c:7
(gdb) s
(gdb) s
(gdb) s
<Crash>

Not 100 % reproducable, but 95 %. I tried on different machines and even different gdb versions. The second machine was Debian GNU/Linux.
