I forgot that even -O1 will optimize over a routine which doesn't
do anything useful with local variables.
Suggestion: I'm betting that
int a = 1, b = 0, c;
c = a / b;
will FPE on you.
I retract that this is a bug in gcc, although I think optimizing over
something like the previous example is a faux-pas.
