Looking at exmpp I see that it contains a linked-in driver. I would
consider that as prime suspect.
Enable core dump generation:
[bash]> ulimit -c unlimited
Run test to generate core dump file.
Look at core dump:
> gdb /path/to/otp-release/erts-x.y.z/beam.smp -c core.xxx
/Sverker, Erlang/OTP Ericsson
