>Description:
Using gdbserver I can not step to the next line (Next) in a thread. I get SIGTRAP. This works fine debugging a program directly without gdbserver. If I run the program with gdbserver and then connect to it with gdb I can hit a breakpoint in the thread but then when I try to do next I get a sigtrap.
Breakpoint 2, BusyWork1 (null=0x0) at foo.c:13
13 result = result + 1;
(gdb) n
Program received signal SIGTRAP, Trace/breakpoint trap.
[Switching to Thread 16384]
0x40099d63 in sigsuspend () from /lib/libc.so.6
(gdb) where
#0 0x40099d63 in sigsuspend () from /lib/libc.so.6
#1 0x40026128 in __pthread_wait_for_restart_signal () from /lib/libpthread.so.0

I tried 20030613 but I couldn't even start the program.
>How-To-Repeat:
Build the attached program.
gdbserver foo:1234 foo
In another window...
gdb foo
