Same result here, with the same processor. There is different (but not correct) behavior with -ffloat-store: $ gfortran -ffloat-store d1mach.f && ./a.out 2.225073858507201E-308 4.882199637915989E-270 5.092789898316654E-312 4.925696698649795E-270 2.79357004253718 -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18518
