If the stride is not equal to one, and if the size can be calculated at compile-time (which the call to gfc_ref_dimen_size checks, and does), then the end of the array reference is set to the minimum. I extended that function to also calculate the end. > What puzzle me is that I > do not see any division, is it hidden in the gmp calls? The division is handled in gfc_ref_dimen_size, where I simply used the size calculatd there to also calculate the minimum end. You'll find the division there. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44235
