--- Comment #8 from Thorsten Kurth <thorstenkurth at me dot com> ---
Here is the output of the get_num_threads section:

[tkurth@cori02 omp_3_vs_45_test]$ export OMP_NUM_THREADS=32
[tkurth@cori02 omp_3_vs_45_test]$ ./nested_test_omp_4dot5.x
We got 1 teams and 32 threads.

and:

[tkurth@cori02 omp_3_vs_45_test]$ ./nested_test_omp_4dot5.x
We got 1 teams and 12 threads.

I think the code is OK.
