--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- It is unspecified what the value of an overflow conversion is. So 1 is correct so is -1 and/or INT_MAX. I don't think this is a bug. The test code which depends on these values is broken and should not be used. I know some "C validation" suites which have this bug for float/double also (I put "C validation" is quotes because they are not validating C at that point but rather an specific implementation of C).
