I suspect you didn't realize that the PR wasn't opened until July; I had no knowledge of it when 3.4 or 4.0 were released. If I had, I would have declared it a showstopper then. Now, it's a showstopper to figure out what happened and make an informed decision. If we conform to a published ABI where we did not before, maybe we do nothing; this is a bug fix. If we now fail to conform to a published ABI, maybe we add a switch. But, we certainly have to evaluate it before the release. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22275
