A.29 Use of Work-Sharing Constructs Inside a critical Construct 

The following example demonstrates using a work-sharing construct inside a critical construct. This example is compliant because the work-sharing construct and the critical construct do not bind to the same parallel region.

void f()
{
  int i = 1;
  #pragma omp parallel sections
  {
    #pragma omp section
    {
      #pragma omp critical (name)
      {
        #pragma omp parallel
        {
          #pragma omp single
          {
            i++;
          }
        }
      }
    }
  }
}
