--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Actually it is worse than you think. The problem is __PTRDIFF_TYPE__ is
defined incorrectly if pointers can span across the sign bit (32bit). There is
whole thread about this on gcc@. The C/C++ language defines ptrdiff_t as a
type which can be used two take a difference of any two valid pointers and get
a signed difference.
In the case here 0x8002000f-0x0001000f should actually return a signed integer
that represents the space between those two pointers.
