Theoretically they may trap SIGSEGV (this is the signal thrown here,
that is "Invalid memory reference", not necessarily stack related).
But I can't immediatelly say whether it may work in this specific case;
at least I can't trap it in a perl script that ran out of stack.

There is a possibility that perl indeed has bugs that lead to quick stack
overflow, in which case you (and the developers) do want core dumped to
debug the problem.
