This does not interact well with passing nonprocedure-pointer functions, that return allocatables, as can be seen from the following chunk in trans-expr.c's gfc_conv_procedure_call: if (fsym && e->expr_type != EXPR_NULL && ((fsym->attr.pointer && fsym->attr.flavor != FL_PROCEDURE) || (fsym->attr.proc_pointer && !(e->expr_type == EXPR_VARIABLE && e->symtree->n.sym->attr.dummy)) || (fsym->attr.proc_pointer && e->expr_type == EXPR_VARIABLE && gfc_is_proc_ptr_comp (e, NULL)) || fsym->attr.allocatable)) Untested patch: Do the same as we already do for pointers. --- trans-expr.c (revision 183625) +++ trans-expr.c (working copy) @@ -3664,3 +3664,4 @@ gfc_conv_procedure_call (gfc_se * se, gf && gfc_is_proc_ptr_comp (e, NULL)) - || fsym->attr.allocatable)) + || (fsym->attr.allocatable + && fsym->attr.flavor != FL_PROCEDURE))) {
