Ah.  I've seen this from time to time.  I'm never 100% sure why you see
a dialog rather than a stack dump.

Initially, I thought it was because a SEGV happened just prior to the
initialization required for trapping an exception but I would swear
that I've seen a dialog pop up when that wasn't the case, too.

Anyway, I'll look at dcrt0.cc and see if the exception handling can be
started a little earlier.
