7 | OMP: Error #13: Assertion failure at kmp_runtime.cpp(1715). |

9 | The assertion fails even with OMP_NUM_THREADS=1. If the second task is removed, |
10 | everything runs to completion. If the "omp parallel for" directives are removed |
11 | from inside the tasks, once again everything runs fine. |
