Bug ID: 83829 Summary: Implement runtime checks for DT format specifier and allignment with effective items Product: gcc Version: 8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: jvdelisle at gcc dot gnu.org Target Milestone: --- As discussed on the gfortran mailing list, we need to hadle the case where a User Defined Derived Type Procedure is provided for formatted I/O but the user chooses not to use it by omitting the 'DT' specifier in a format string. See thread here: https://gcc.gnu.org/ml/fortran/2018-01/msg00032.html. The patch for pr82007 eliminates the rejecting of valid code.
