Dear Jerry, > Committed as trivial.
Many things are trivial unless noted otherwise! The patch causes the following failures: FAIL: gfortran.dg/inquire_13.f90 -O0 execution test FAIL: gfortran.dg/inquire_15.f90 -O0 execution test FAIL: gfortran.dg/inquire_6.f90 -O0 execution test FAIL: gfortran.dg/inquire_9.f90 -O0 execution test FAIL: gfortran.dg/large_unit_2.f90 -O0 execution test FAIL: gfortran.dg/make_unit.f90 -O0 execution test FAIL: gfortran.dg/negative_unit.f -O0 execution test FAIL: gfortran.dg/negative_unit_int8.f -O0 execution test FAIL: gfortran.dg/pr20950.f -O0 execution test see, e.g., https://gcc.gnu.org/ml/gcc-testresults/2016-10/msg00375.html. Also the test gfortran.dg/dtio_15.f90 succeeds even with revision r240768 reverted. Thanks for working on the issue while waiting for the four character fix! Dominique
