Hm, weird that it only shows up in `5.3.6`.

The `$regex = $this->_regex` assignment doesn't really need to be a reference for any *functional* reason, upon inspection of the code; I assume that copy-on-write applies to lexical variables imported in to the scope of a closure (as done above) as well.
