--- Comment #2 from mikulas at artax dot karlin.mff.cuni.cz --- Created attachment 30362 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30362&action=edit another reproduction code The code in the first attachment actually did some out-of-memory accesses because I simplified it too much. This is the second attachment that should be correct.
