With a newer gdb, you can instead tell gdb to follow all forks. I wrote
some notes on it recently.

I've found it really handy when debugging crashes in regression tests.

However, it's often simpler to just:

ulimit -c unlimited
make check

(or whatever your crashing test is) then look at the core files that are
produced.
