Confirmed. No crash in Perls 5.8 to 5.14, but crashes in 5.16. Tried it in threaded and unthreaded Perls and same results.

Hmmm... I really need to grab 5.17.x for testing things like this.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
