Likely 32bit issue in Parallel Accelerator code. #2372
Description
The ParallelAccerator technology code (#2318) is failing to pass all the tests on a few of the Numba build machines. The pattern to the failures seems to be for OS windows 32bit and linux x86, and for all Numpy and Python version combinations.
Opting to drop a lot of irrelvant backtrace, the key failures are:
