--- Comment #36 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- Created attachment 30782 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30782&action=edit Next try for a fix OK, I removed the misalign code path completely, and found a one-line fix for read side too. So here is my next try to fix this issue. It seems to boot-strap on x86_64 and all test cases pass. Additional testing would be welcome. Any comments?
