# True, but the compiler should warn about bogus source code, even if the
# resulting object code (depending on optmiziation flags) is valid.
Yes, but this type of warning needs data flow analysis, which IIRC is
documented to need at least -O1. So I suspect the original code may have
been compiled without optimization.
