perldoc perldiag:
Deep recursion on subroutine "%s"
(W recursion) This subroutine has called itself (directly or
indirectly) 100 times more than it has returned. This probably
indicates an infinite recursion, unless you're writing strange
benchmark programs, in which case it indicates something else.
It works as described for me. Perhaps your test sub isn't doing what you
think it's doing, or perhaps you forgot to turn on warnings?
