// This test checks that C++ destructors are not called when an
// uncaught exception occurs.
//
// The C++ standard makes it optional whether destructors are called
// in this situation.  It is more convenient for debugging if
// destructors are not called, because unwinding the stack to call
// them would lose the context of where the uncaught exception was
// thrown from.
