--- Comment #10 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- The test cases I have been working on uses: read( unit=s, fmt='(dt)', iostat=istat, iomsg=imsg, pad='yes' ) foo versus: read( unit=s, fmt=*, iostat=istat, iomsg=imsg, pad='yes' ) foo With fmt=*, the first character is still getting eaten and I think is related to parent. Needless to say, this PR has uncovered multiple issues so is taking me a lot of time.
