--- Comment #1 from Allan Jensen <linux at carewolf dot com> ---
Sorry forget the example above. I will attached the real code that triggers it.
Note it does not trigger with -fno-signed-zeros, -fno-trapping-math,
-fassociative-math and -freciprocal-math, so it is something specific to
unsafe-math-optimizations itself.
