  * resolution:  => invalid

Comment:

 The program throws a std::runtime_error because the match was taking too
 long to find - without a try-catch block around the code there is a stack
 error (I don't understand that one), but with a try-catch block the
 exception is caught and everything is behaving as expected.

 Is there a reason for the leading .* in the expression?  It serves no good
 purpose other than to make the expression harder to match - you can get
 the same information from match_results::prefix() and way better
 performance.
