This is 4.2-specific stuff. We should handle "force_align_arg_pointer" function attribute.

This is a bug, but doesn't block 1634.

Actually, we can easily ignore this attribute. New stack realignment code handles this case (attribute was introduced to workaround poor gcc's stack realignment support) without any problems.
