## Known issues

There is a known issue with random crashes with Node 14 and 16 on macOS. See here:
- https://github.com/nodejs/node/issues/32463
- https://github.com/node-ffi-napi/node-ffi-napi/issues/97
- https://github.com/node-ffi-napi/ref-napi/issues/47

It seems to work with Node 12 on macOS, as well as on other platforms.
