Purify already handles pad bytes added for alignment correctly. This is a very specific case, where the pad byte is added to prevent the struct from having size zero, not for alignment. The added code to clear 1 byte, at object constuction time, would not make any significant performance difference. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38107
