My naive guess that -fcheck-references is worse because it's going to
impact nearly every method, whereas try...catch blocks are relatively
infrequent (at least in my code).

On the other hand, -fcheck-references doesn't require a memory access,
just a test/branch.

It'd be interesting to benchmark each on a real program, something like
the Xerces parser.
