This test will fail if the version is not 2.2.0 or newer. If you have a good mpfr, then the problem may be similar to the one with nearest_1.f90 where the extra precision in the registers is bad (ie., add -ffloat-store to the test). One other possibility is the problem with subnormal numbers is also affecting this test. I hope to look into the subnormal issue later today. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29317
