The nature of the hang is the issue. If for example the illegal sequence
causes a trap to the wrong vector and has invalid and predictable contents
on the stack, the damage is limited to special casing that trap. (Note
that this is not a claim that this, specifically, is what's happening.)
My point: I can imagine a couple ways to hang the system when the CPU
behaves unexpectedly. If you understand what happens when it does, you
have a chance to work around the problem.
