That's why the proposal is about __try/__finally only, not __except
where it is e.g. not clear at all what happens if you throw in C++
and __except control expression returns -1.
At least from what I read in MSFT docs on the web, their __try/__finally
matches Aldy's patch.
Except that it also handles asynchronous exceptions, which ours doesn't.
Where we'd get a SIGFPE you get a structured exception in Microsoft's
That has nothing to do with the semantics of try/finally, which just deals
with cleaning up after whatever exceptions do happen to be thrown.
This horse is pretty dang dead, but the point is that people will *expect*
that the construct behaves the same way as Microsoft's "structured
exception handling" stuff -- in every way.  Part of that is handling
SIGFPE type events.
