Assertion failure at kmp_runtime.cpp(1715): nthreads > 0.
OMP: Error #13: Assertion failure at kmp_runtime.cpp(1715).
The assertion fails even with OMP_NUM_THREADS=1. If the second task is removed,
everything runs to completion. If the "omp parallel for" directives are removed
from inside the tasks, once again everything runs fine.
