(Windows only) "access violation" when running simulations with custom kernels

parcels 3.0.4

When running on Windows, occasionally (without seeming to have changed any code) one can run into an access violation error.

E.g.,

OSError: exception: access violation reading 0x00000186DEE83138

It's an issue we've encountered a few times before (#793 , #1232). This issue is due to the conversion of the kernels to C, although why this would only crop up on Windows is a mystery to me

First step is to come up with a minimal reproducible example.
