I've always found the naming of trap 0 interesting. My experience that it
occurs more often when the dividend is too large.

When the dividend is too large and/or the divisor is too small.
Remember the old Borland runtime library error 200 on faster (of the day) CPUs?
That was a 'divide by zero' error where it wasn't dividing by zero.

The meaning of the exception is actually 'divide overflow' - it's just that
it is usually caused by dividing by zero because that always generates that
exception.

I can see user programs doing that, and they can crash without taking down
the system.

What you see is irrelevant, Tholen.

Further proof that you are a troll, nobuyout. You're so obsessed that
you're following me around to another newsgroup.

But shouldn't the system protect itself from such a crash by
testing for the exception and avoiding it?

Only if the software engineers programmed such a test into the system,
Tholen.

Classic begging of the question. But not unexpected from a troll who
has no real intent of addressing the issue at hand.
