It has been a long time since I looked at this, but this example:
```
PROGRAM main
    IMPLICIT NONE

    TYPE :: dt 
        REAL, POINTER :: p(:)
    END TYPE dt

    TYPE(dt) :: xdt 
    REAL, TARGET :: t(10)

    xdt%p => t(:)

    !$omp target map(xdt)
    PRINT*, ASSOCIATED(xdt%p)
    !$omp end target
END PROGRAM main
```
outputs `T` for `ASSOCIATED(xdt%p)`, which was the original example I tried to replicate in https://github.com/llvm/llvm-project/issues/176956. This result goes against what is mentioned in https://www.openmp.org/wp-content/uploads/OMP-Users-Monthly-Telecon-20211210.pdf on page 15. That would mean it is not fixed yet. I am running on a flang build from today on an NVIDIA gpu.
