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:

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