            Bug ID: 106561
           Summary: gfortran.dg/ieee/signaling_1.f90 fails with
                    --with-long-double-format=ieee
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other

This happens for both gcc 12 and 13 (trunk) and started when the test case was
added.

It occurs on powerpc64 LE with the compiler configured with
--with-long-double-format=ieee on Fedora 36 which is the first powerpc64 distro
built with --with-long-double-format=ieee.  It works fine on other distros even
with --with-long-double-format=ieee so it could be a problem with the distro
compiler, gcc version 12.1.1 20220507 (Red Hat 12.1.1-1) (GCC), or maybe the
libraries.
