See http://gcc.gnu.org/ml/fortran/2009-08/msg00390.html :

I have dug the problem a little bit more and found that the key
option is -funsafe-math-optimizations. I tried to refine that, but as
usual this option is not the sum of -fassociative-math -fno-signed-zeros
-fno-trapping-math -freciprocal-math as said in the manual!-(
