Strangely, I don't see a core dump file. If I comment out the use Data::Dumper; line, or if I move that line above the use Switch; line, I don't see the segfault error. It looks like if the Switch line is last, we get no errors.

I realize Switch is strongly discouraged, and I will attempt to convince the original code author to get rid of it.
