This question would be more appropriate on the mailing list
gcc-h...@gcc.gnu.org. The mailing list gcc@gcc.gnu.org is for
discussions about the development of GCC itself. Please take any
followups to gcc-help. Thanks.
That said, I think this case is a bug. Please report it following the
instructions at http://gcc.gnu.org/bugs. Thanks.
