I also found edge cases in parallel code.

One loop that didn't have any invalid reads or writes segfaulted in a numba prange (eg. Openmp) loop.

Just reimplementing a loop as a few smaller subfunctions called sequentially worked.

No clue where the optimizer got confused on the 20 line loop body before it got split -- it's the same code.
