The exp test case fails on s390(x) for the dd_real type. It used to pass fine in the F-16 days, so I suspect it can be gcc related. The last successful build used gcc 4.6.3, later ones with gcc 4.7 and 4.8 are failing due the exp test. [sharkcz@devel6 tests]$ ./qd_test -v Testing dd_real ... sizeof(dd_real) = 16 Test 1.
