The relevant python code seems to be

412     trees = random_forest(
413         dataset[:train, :],
414         max_depth,
415         min_size,
416         sample_size,
417         n_trees[1],
418         n_features
419     )

Where random_forrest is a phylanx function.

Not sure how to make a small test out of this. I am attaching the source.

This is an HPX problem. I created a ticket here: STEllAR-GROUP/hpx#5118.

@stevenrbrandt would you be able to show the back-traces for all threads? the one above is not from the thread that fails.
