Erratic? It should have given a specification
exception, shouldn't it? 3/4 of the time.

I'm surprised about that too. That should have
failed too, shouldn't it?

I think an ICM B'1111' is required for this.

Two of them.

And what makes you think it is ARM-specific? It
might be a Herc bug if it's not abending on the

that. Which would make a separate VM bug.

Or am I missing something?
