I don't understand the problem: [Book15] f90/bug% gfc iso_c_2.f90 -fdump-fortran-original Namespace: A-Z: (UNKNOWN 0) procedure name = MAIN__ symtree: 'C_funptr' || symbol: 'c_funptr' type spec : (DERIVED c_funptr) attributes: (DERIVED BIND(C) USE-ASSOC(__iso_c_binding)) components: (c_address (INTEGER 8) () PRIVATE) symtree: 'C_ptr' || symbol: 'c_ptr' ... Am I correct that the problem occurs only when running implicit_class_1.f90 under dejagnu?
