It is since my recent patch to do all alignment calculation for fields in
layout_decl.  Unfortunately, previous releases gave the wrong answer, and I
haven't moved that patch into 3.3.  It should be possible to fix this more
simply in 3.3 by adding

 DECL_ALIGN (field) = desired_align;

to the end of update_alignment_for_field.
