Yury V. Zaytsev added the comment: After lots of fiddling, I can tell you what's wrong with the macro: apparently it's a compiler bug, visible at -O2 and disappearing at -O1.
Assembly output is attached, unfortunately, I'm no ppc64 expert, so I can't immediately tell what exactly went wrong. In any case, the first half of the bug (missing check for HAVE_LETOH64) which triggered the second half still seems valid. I think it's not feasible to upgrade the compiler on RHEL 6.5 (unless someone with a subscription wants to have a go), but fixing the first part should avoid the compiler bug altogether. ---------- Added file: http://bugs.python.org/file33345/le64toh.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20162> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
