>Description:
When a break point is hit by a thread created with the pthreads library (NPTL) the following is displayed on the GDB console:
Program terminated with signal SIGTRAP, Trace/breakpoint trap.
The program no longer exists.
No further debugging is possible. I've also verified that the problem happens when running on the stock SuSE 9.3 kernel (2.6.11.4-20a-smp)
