Division by 0 is undefined behavior. A platform may transform it into
an exception, but that certainly isn't a requirement.

Passing 0 here is undefined behavior. A platform ...


In both cases, the program is in an invalid state after the attempted
operation, and IMHO, anything but immediate termination of the program
is (at least) weird.
