Bug Description
There's a bug in GCC 4.8 related to vectorization of dot product-like code: http://
4.8 is the only upstream branch that's affected, however, you seem to have backported the revision introducing the bug (r185437) into 4.6 and 4.7 as well, and those are now affected as well. Since the fix is already available (r202663), please backport it to the affected branches.
