The Fortran compiler front-end now diagnoses conflicts between PROCEDURE and ALLOCATABLE attributes on function results before they are redirected to a hidden procedure pointer. This change ensures that attribute conflicts are checked against the original declaration, leading to more accurate and understandable diagnostics for developers.
