If the variable is implicitly firstprivatized in the inner task-based region, it also must be firstprivatized in outer task-based regions. Previously firstprivates were captured in tasks but later it was optimized to reduce the memory usage. But still need to mark such variables as implicit firstprivate in outer tasks.
