It is a veneer which has just a jump and a word after it, which points
to a place in memory that had which I believe was the implementation
of the asan check.

I was wondering if the no_return on that veneer was meant to jump to a
no_return function or just that the veneer itself doesn't return
(which would be silly).

It's possible that the asan check has a no_return attribute but for
some reason it returns? Wouldn't the compiler warn/err on that?
