Consider the following code
```
type A (p, r)
integer, kind :: p, r
real (selected_real_kind(p, r)) :: data
end type
type(a(6,23)) :: a1
print*, a1%data%kind
end
```
Flang failed at the compile time with
```
error: Semantic errors in t.f
./t.f:3:15: error: Must be a constant value
real (selected_real_kind(p, r)) :: data
^^^^^^^^^^^^^^^^^^^^^^^^
```
All ifort, gfortran and XLF compile and execute the code successfully.
The folding of `selected_real_kind` could occur when the type is instantiated.
