You can paste the expanded cpp file on gist.github.com.

nikic · 2022-01-10T14:04:52Z

I pushed a speculative fix at 7725331, maybe it will be sufficient.

nikic · 2022-03-03T14:15:00Z

Just want to check back here whether you're still seeing issues on Windows?

russellw · 2022-03-12T01:17:04Z

Yes, that seems to work now, thanks!
