Comment 1 Marek Polacek 2015-05-11 09:36:20 UTC 
Started with r211625, reproduced even with GCC trunk.  I don't think we have a PR for this, so will reduce & open a PR.

As for the fix, I think we're forgetting to mark some loop for fixup.
Comment 2 Marek Polacek 2015-05-11 10:18:45 UTC 
Tracking in PR66101.
