I have opened bug BZ#15268. I couldn't find a easy way to add a testcase in the
existing math mainly because although the exp call underflow, the result is
not inexact and the underflow mask is set on test-* cases to not trap. I open
to suggestion on how to add a testcase or if is really need to add one.
Nevertheless I still do think the current default behavior of holding exception
for SET_RESTORE_ROUND is wrong and it leads to different semantics across
