Dear Uros, Thanks for that. It is not a problem that I encountered on either the 32 bit or 64 bit machines that I use but, as you say, an underflow is the most likely explanation. I guess that without any loss, as far as the test is concerned, a test that obj%c(i,j) is greater than 1e-5, say, could have been done before raising it to the fourth power!

Hello! -mieee is needed for this runtime test to avoid FAIL: gfortran.dg/typebound_operator_8.f03 -O0 execution test FAIL: gfortran.dg/typebound_operator_8.f03 -Os execution test on alpha-linux-gnu.
