I would actually recommend solving the problem in its root.

Disable auto vectorization.

FFmpeg recently tried removing "-fno-tree-vectorize" for gcc >=4.9 .
After a few weeks they reverted the change.
It caused a bunch of strange regressions, breakages and ICE.

That features has been around for nine years and it is still buggy.
Save yourself some headaches and disable it.
