My guess is your gdb has no support for debugging threaded programs:

"On most systems, GDB has no special support for debugging programs
which create additional processes using the `fork' function.  When a
program forks, GDB will continue to debug the parent process and the
child process will run unimpeded.  If you have set a breakpoint in any
code which the child then executes, the child will get a `SIGTRAP'
signal which (unless it catches the signal) will cause it to  
terminate."

using gdb command "handle SIGTRAP ignore" may help - I do not know.
