--- Comment #3 from Jason Merrill <jason at gcc dot gnu.org> 2011-06-28 06:31:11 UTC ---
constexpr-ptrmem.C is now failing because the C++ ABI uses the low bit of the
function pointer field in a pointer-to-member function to indicate whether that
field is actually a function pointer or a vtable index, and constexpr-ptrmem.C
relies on being able to fold (&fn) & 1 to 0.

I assume that the ARM C++ ABI variant uses a different representation.
