            Bug ID: 79523
           Summary: valgrind error for
                    gcc/testsuite/gfortran.dg/dtio_13.f90
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

I just tried to compile the above test case with a valgrind version
of recent trunk gfortran. 

$ /home/dcb/gcc/results.245439/bin/gfortran -c   gfortran.dg/dtio_13.f90 

Ok the fortran produces error messages, but also

==32156== Invalid read of size 1
