Apparently -ffast-math generates incorrect code with recent versions of GCC and Clang. The manual page for GCC warns about this possibility. In my tests it doesn't actually appear to be measurably slower in this case, and this is used in a batch process so it seems safe to disable this. This fixes #10758 and fixes #10070
