CTest WILL_FAIL segfault SIGABRT catch

By design, CTest WILL_FAIL test property does not handle segmentation faults and other unexpected terminations. That is, a failing test will also show as failed in CTest, when the desire may have been to show an intended failure as success via WILL_FAIL. A simple workaround for this is to make a wrapper call for the intentionally segfaulting executable and catch that result, as in example project.
