Thank you for reporting this issue. I am very interested in finding the root cause of this issue. Can you change the test in the conda recipe to:

assert bitarray.test(verbosity=2).wasSuccessful()

and post the output? This will give me a much better hint where the problem is. Thanks

Looking into this some more, I think the problem is in shift_r8(), when undefing PY_UINT64_T things work fine on s390x.
