Tobias Burnus <burnus at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |wrong-code --- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> --- Actually, the patch is sufficient as one then runs into a tree checking error: class_array_20.f90:21:0: error: non-trivial conversion at assignment struct array1_unknown struct array2_integer(kind=4) if one looks at the dump, one sees that the actual argument still sends the array descriptor - but it shouldn't: parm.7.dim[0].lbound = 1; ... parm.7.data = (void *) &b[0]; class.6._data = parm.7; mysub (&class.6, &C.1946); Thus, the test case also doesn't work for rank == 1, if one checks the value. TODO * Sends in _data the array data, not the descriptor * Add a test case for the coindexed part of the patch below. * Augment the test case in comment 0 with a value check Updated patch: --- a/gcc/fortran/interface.c +++ b/gcc/fortran/interface.c @@ -2135 +2135,5 @@ compare_parameter (gfc_symbol *formal, gfc_expr *actual, - || (actual->rank != 0 && !(is_elemental || formal->attr.dimension)) + || (actual->rank != 0 + && !(is_elemental + || (formal->ts.type != BT_CLASS && formal->attr.dimension) + || (formal->ts.type == BT_CLASS + && CLASS_DATA (formal)->attr.dimension))) @@ -2142 +2146,4 @@ compare_parameter (gfc_symbol *formal, gfc_expr *actual, - || (actual->rank == 0 && formal->attr.dimension + || (actual->rank == 0 + && (formal->attr.dimension + || (formal->ts.type == BT_CLASS + && CLASS_DATA (formal)->attr.dimension)) @@ -2150 +2157,4 @@ compare_parameter (gfc_symbol *formal, gfc_expr *actual, - else if (actual->rank != 0 && (is_elemental || formal->attr.dimension)) + else if (actual->rank != 0 + && (is_elemental || formal->attr.dimension + || (formal->ts.type == BT_CLASS + && CLASS_DATA (formal)->attr.dimension)))
