Guarding ref->u.ar.as is good practice. However, it turns out that the associate name symbol has a perfectly good array_spec. This version "double fixes" the PR and is somewhat more satisfactory. diff --git a/gcc/fortran/resolve.cc b/gcc/fortran/resolve.cc index 83e45f1b693..9863cdc1583 100644 --- a/gcc/fortran/resolve.cc +++ b/gcc/fortran/resolve.cc @@ -5640,7 +5640,12 @@ gfc_expression_rank (gfc_expr *e) if (ref->type != REF_ARRAY) continue; - if (ref->u.ar.type == AR_FULL) + if (ref->u.ar.as == NULL + && e->expr_type == EXPR_VARIABLE + && e->symtree->n.sym->as) + ref->u.ar.as = e->symtree->n.sym->as; + + if (ref->u.ar.type == AR_FULL && ref->u.ar.as) { rank = ref->u.ar.as->rank; break; Gratifyingly, this does the right thing: implicit none type tlap real, allocatable :: z(:) end type tlap type(tlap) :: y_in real :: x_out(3) =[0.0,0.0,0.0] integer :: pid = 1 y_in%z = [1.0,-2.0,3.0] call foo(y_in, x_out) print *, x_out call foo(y_in, x_out) print *, x_out contains subroutine foo(y, x) type(tlap) :: y real :: x(:) associate(z=>y%z) if (getpid() == 1) then where ( z < 0.0 ) x(:) = z(:) else where ( z > 0.0 ) x(:) = z(:) endif end associate end subroutine foo integer function getpid() getpid = pid pid = pid + 1 end function getpid end Cheers Paul Referenced Bugs: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87477 [Bug 87477] [meta-bug] [F03] issues concerning the ASSOCIATE statement
