Uhm that shows my limited understanding of gcc options. I think you are correct that it needs 
more than -O0 though I don't even know how to test that.

Since I have this set I don't have any -Ox in CFLAGS anymore.

My gcc is 4.8.2 by the way. But I saw the same error the one time I built with clang a couple of 
days back.
