JRE detects `EXCEPTION_ACCESS_VIOLATION` when trying to use Verilator as Chiseltest's backend

When trying to use Verilator as Chiseltest's backend, I got the following error messages:

My OS is Windows 11. I'm using Verilator v4.202 (via MSYS2), Chisel3 v3.6.0, and Chiseltest v0.6.0. I have no trouble using Chisel to generate Verilog files, nor using Treadle as Chiseltest's backend. However, I'm struggling to get Chiseltest using Verilator on Windows.

The full error report hs_err_pid9936.log is here. Any advice would be deeply appreciated.

Looks like the JNI component that we use to load Verilator simulations does not work properly on your Windows system. Unfortunately Windows support (especially for the native simulators) is somewhat "best effort" and mostly relies on Windows users debugging problems and submitting pull requests with fixes. Personally I do not have the experience nor time to debug Windows problems.

This was the last such PR that seemed to make chiseltest work on windows for the author: https://github.com/ucb-bar/chiseltest/pull/507
