Will look at it now that there's a reproducer I can use. |
Here's a smaller reproducer with just 3 tests:

Doing:
then installing Numba from master, then... for i in `seq 0 10000`; do export PYTHONHASHSEED=${i}; echo "HASHSEED=${PYTHONHASHSEED}"; python -m numba.runtests -vfb numba.tests.test_parfors.TestParforsSlice.test_parfor_slice3 numba.tests.test_parfors.TestParfors.test_reduction_var_reuse numba.tests.test_parfors.TestParfors.test_fuse_argmin; done Having |
Interesting. Mine triggers at 13. |
