Not sure if Flang frontend has full support of the Length type parameter of PDT. If not yet, I am happy to close this issue and mark the test case.
Consider the following code:
```
MODULE Mod
IMPLICIT NONE
TYPE :: Base(k1, l1)
INTEGER, KIND :: k1 = 1
INTEGER, LEN :: l1 = 1
INTEGER(k1) :: A0(l1) = -1
CHARACTER(l1) :: C0 = 'Base'
END TYPE
TYPE, EXTENDS(Base) :: Child(k2, l2)
INTEGER(k1), KIND :: k2 = k1
INTEGER(k1), LEN :: l2 = k1
CHARACTER(l2+3) :: C1 = 'Child'
END TYPE
TYPE, EXTENDS(Child) :: NextGen(l3)
INTEGER(k2), LEN :: l3 = k2
CHARACTER(l3) :: C2 = CHAR(k2)
INTEGER(k2) :: A2 = k2
TYPE(Base(k2, l3)) :: cmp
CLASS(Base(k2, l3)), POINTER :: ptr
END TYPE
CONTAINS
SUBROUTINE CheckNextGen(Obj,Arg)
CLASS(NextGen(4,*,4,*,*)) :: Obj
TYPE (NextGen(4,*,4,*,*)) :: Arg
END SUBROUTINE
END MODULE
```
Flang issues a set of error messages starting at
```
error: Semantic errors in t.f
./t.f:8:26: error: Shape of initialized object 'a0' must be constant
INTEGER(k1) :: A0(l1) = -1
^^
./t.f:31:10: in the context: instantiation of parameterized derived type 'base(k1=4_4,l1=*)'
CLASS(NextGen(4,*,4,*,*)) :: Obj
....
.....
```
