I can't change that. > I receive a sequence of digits, and I should output a number. My mistake. It should surprise no-one that handling pathological input cases is no picnic.

There's a lot of talk about "undefined behaviour" in non- conforming C but "unexpected behaviour" ought to get honorable mention even if it does not fully depend on non-conformance.
