           Summary: [8 regression] libgomp.fortran/pointer[12].f90 FAIL
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

Between 20180112 (r256571) and 20180114 (r256664), two libgomp tests started to
FAIL.  I'm seeing it on Solaris/SPARC and x86, but according to
gcc-testresults,
it happens (almost) everywhere:
