--- Comment #3 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Sigh, this is a PCS layout bug for argument marshalling. I think it can only
happen when a struct inherits 64-bit alignment from a bit-field. In this case,
the alignment on the bit-field is 1, but it's real alignment for the purposes
of type-layout is derived from the bit-field's type.
I have a simple fix, but I need to think a bit more about how we might need to
warn about this change occurring - made more complicated by the fact that we
already have code to warn about a previous ABI bug in this area.
