Nope. If it failed, it'd raise a SIGILL, I think. And it still wouldn't
be a problem, as it's the whole point of the test to provoke a signal
and catch it.
The submitter correctly continued and captured a backtrace of the actual
problem. The information you asked for will still be useful, and I
suspect the backtrace might be more accurate with something like
electric-fence.
