--- Comment #8 from Paul Thomas <pault at gcc dot gnu.org> --- A temporary fix: Index: ../trunk/gcc/fortran/trans-io.c =================================================================== *** ../trunk/gcc/fortran/trans-io.c (revision 257261) --- ../trunk/gcc/fortran/trans-io.c (working copy) *************** gfc_trans_transfer (gfc_code * code) *** 2590,2596 **** if (expr->ts.type != BT_CLASS && expr->expr_type == EXPR_VARIABLE ! && gfc_expr_attr (expr).pointer) goto scalarize; --- 2590,2596 ---- if (expr->ts.type != BT_CLASS && expr->expr_type == EXPR_VARIABLE ! && (gfc_expr_attr (expr).pointer || gfc_expr_attr (expr).allocatable)) goto scalarize; fixes this and pr84141. transfer_array is receiving a dtype with all the fields set to zero. I will get back to this tonight or tomorrow morning. I have to go to the lab now. Paul
