It's a murky area of the C ABI but I don't think the implementation has
changed.  I know gcc and Intel's C compiler were at disagreement over
that one at one point.  But I would have to read through the release
notes to see.

If gcc has changed on x86 it is even more important that the field is 
not implemented as a uint64_t.  Because unfortunately it is preceded
by a 32bit number which means that field should only be 32bit aligned.
