------- Comment #18 from howarth at nitro dot med dot uc dot edu  2009-08-28 01:09 -------
Why don't you go back to the original test case and see which component of
-funsafe-math-optimizations...

-fno-signed-zeros -fno-trapping-math -fassociative-math -freciprocal-math

is actually causing the problem.
