  This is a feature: CrashReporter's developer mode (not enabled by
  default, but I like it very much, as I can now know when a process
  has crashed). See:

No, it's not a feature, it's a bug.  :-)

  The exception was EXC_BAD_INSTRUCTION. Then, I don't know, except
  that the standard config.guess doesn't crash.

OK, I think I see what is going on.  The mfpvr instruction causes
a protection fault on Mac, AIX, and NietBSD, as mentioned in a
comment in config.guess.

I doubt there is any good fix for this.  You asked to have popup
window for every Unix signal, and you get what you ask for.

  I can't currently
  check more closely, because my Power Mac died last night (probably
  the power supply) :( and I'm off for the next two weeks.
Perhaps config.guess triggered a self-destruct *feature* of your
Mac.  :-)
