--- Comment #1 from Joseph Myers <jsm28 at gcc dot gnu.org> ---
The C99 requirement to raise divide-by-zero in this case was a defect, as it
was contrary to IEEE 754 semantics for that exception.  See N1515.  Thus, it's
a defect in POSIX that it hasn't adopted the C11 correction, and the ideal
result would be *never* raising that exception in this case.
