    If a common block symbol is not used in a threadprivatised directive, a LLVM symbol error is thrown.

```
  program sample
  integer:: x
  integer :: y
 common /blk/ x
  !$omp threadprivate (/blk/)
  !$omp parallel sections copyin(/blk/)
    !$omp section
      y = y + 1
  !$omp end parallel sections
 end program sample
```
