            Bug ID: 16427
           Summary: test-ldouble and test-ildoubl fail on S/390
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: krebbel1 at de dot ibm.com
                CC: drepper.fsp at gmail dot com

Even after regenerating ULPs test-ldouble and test-ildoubl keep failing.

This worked with glibc 2.14 and fails with 2.17. It still fails with 2.19. I'll
try to start some more tests in order to narrow it down.
