I don't know if I was born stupid, but I certainly wasn't born with your quick wits and talent for words, so I'll express myself plainly: using gdb to trace processes which fork, and especially processes which track their children closely, such as shells, has never worked properly in FreeBSD. The reason I know this is that I have spent the last ten years rooting around the FreeBSD kernel, and written or rewritten a sizeable portion of the ptrace(2) code, which gdb uses, myself.
