You're using an outdated version of gdb and you're seeing this phony
SIGSEGV because of it.  There is no actual segmentation fault here, it's
only an artifact of gdb.  You can "continue" past it, or better, use an
up-to-date version that doesn't suffer from this.  This has nothing
whatsoever to do with perl at all, you can trigger it with a hello-world
program too.
