Version of flang : 21.0.0(f75126eeabba13ce2aab53c2e4296fca12b9da0d)/AArch64
```
When `argument keyword (X=)` is used as argument to an extension `sizeof` intrinsic function, a compilation error occurs.
The following are the test program, Flang, Gfortran and ifx compilation/execution result.
sngts014_22.f90:
```fortran
program main
call s2
print *,'pass'
contains
subroutine s2
integer,parameter::pi41=sizeof(X=1)
integer::i41
if(pi41/=sizeof(X=i41)) print *,'err11'
end subroutine s2
end program main
```
```
$ flang sngts014_22.f90; ./a.out
error: Semantic errors in sngts014_22.f90
./sngts014_22.f90:6:36: error: unknown keyword argument to intrinsic 'sizeof'
integer,parameter::pi41=sizeof(X=1)
^
./sngts014_22.f90:8:21: error: unknown keyword argument to intrinsic 'sizeof'
if(pi41/=sizeof(X=i41)) print *,'err11'
^
$
```
```
$ gfortran sngts014_22.f90; ./a.out
pass
$
```
```
$ ifx sngts014_22.f90; ./a.out
pass
$
```
