Wayward Heart a73f9ccc1f Prevent memory leaks from rb_raise
rb_raise calls longjmp, which bypasses C++ destructors, and also keeps the error for catch blocks from being unallocated if passed by reference, which we do for exceptions.

Some of the calls I left can still jump out of try blocks, which you're not supposed to do, but there shouldn't be any objects with destructors initialized at those points so it's probably fine.
