That's because the first non-paren forces it to recurse into the second branch until you hit REG_INFTY or overflow the stack. Swap second and third branches and you have a better chance: $re = qr{ \( (??{$re}) \) | (?> [^()]+) | (??{$re}) (??{$re}) }x; (I haven't checked that there aren't other problems with it, though.)
