Are you stepping or continuing when this occurs?
There is a point, somewhere around where gdb is forking the child,
where stepping always hangs for me. I don't remember exactly where.
I work around it by setting a breakpoint somewhere just after, and
continuing.
It's been a while since I've done this... but see if that helps.
