Version of flang : 21.0.0(3e6f618e86f5fbad2c2d5802416ec3d3366a2837)/AArch64
```
When `component-name (cy1)` declared in `declaration-type-spec (class)` with `pointer attribute` is used as an argument to `entry statement`, a compilation error occurs.
The following are the test program, Flang, Gfortran and ifx compilation/execution result.
snggr249_22.f90:
```fortran
module m3
type x1
integer::ix1
end type x1
type,extends(x1)::x2
end type x2
type,extends(x2)::x3
end type x3
class(x1),pointer,dimension(:)::cy1
contains
subroutine dummy()
entry chk(c1)
class(x1),dimension(3)::c1
end subroutine dummy
end module m3
subroutine s1
use m3
type(x1),target::ty1(3)
ty1%ix1=[1,2,3]
cy1=>ty1
call chk(cy1)
end subroutine s1
program main
call s1
print *,'pass'
end program main
```
```
$ flang snggr249_22.f90
error: loc("/work/home/ohno/CT/test/fort/tp/reproducerJ/PETA_V1020_PT3_FFE02/snggr249_22.f90":13:28): 'hlfir.declare' op for box address must not have a shape operand

```
$ gfortran snggr249_22.f90; ./a.out
pass

```
```
$ ifx snggr249_22.f90; ./a.out
pass

```
