Yeah this is a violation of the spec and must be a bug in ICC. That being
said, is there a practical benefit of checking the validity of the
alignment, except finding buggy object files early? I mean, if an object
file is in an static archive, all "aligned" data in the object file might
not be aligned against the beginning of the archive file.
