[Bug nptl/5392] New: Gdb doesnt stop in breakpoint and displays Program terminated with signal SIGTRAP, Trace/breakpoint trap

I have a simple program dynamically linked against pthread.
I start the program and then attach and set a breakpoint in a child thread.
When breakpoint is reached the message
Program terminated with signal SIGTRAP, Trace/breakpoint trap
is displayed, core is dumped and gdb doesnt stop
It looks like gdb doesnt stop on its own breakpoints if these are sent in child
pthreads
I filled a bug in glibc because:
1. I also tried using Intel debugger (IDB) and happens also.
2. This problem started after i upgraded to glibc 2.6.1. Before everything was fine
3. I changed several kernels some of which stopped at breakpoint before i
upgraded glibc
4. I also changed some gdb compilations also.
Thanks ...please take care of this because is very urgent. I cannot work!!!!!
