Ohh fingers crossed, but from a glance seems relevant.

Just tried out using the binary from CI artifacts, and it does fix the issue!
Is it worth adding a regression test or do you think something so small won't get repeated?

It's already noticed by testing, so no need to add a new test I think. The problem is we can't enable windows tests on CI as several other failures exist. One option might be to try to enable at least some tests as they pass.

Oh, I see, I thought it was something not covered by tests. Are those generic failures? How hard would it be to fix them?

Either way, yeah, at least enabling some tests could be better than nothing. (not in scope of this PR though)

There is at least #2781, an issue with translate-to-fuzz (the output is not as expected - perhaps order of operations issue in fuzzing.h, we've seen such issues before), and after that I saw there was at least one more issue that I didn't investigate.

Not sure how hard they are to fix. Complicating this is that I don't have a windows machine and can't seem to access the normal windows VM I've been using. I'll look into that, but meanwhile I debugged this particular issue using CI here. Would be good if someone with a windows machine could find some time for this.

Complicating this is that I don't have a windows machine and can't seem to access the normal windows VM I've been using.

I think a VM I mentioned earlier on the issue should be enough for such sort of debugging and it includes most of necessary tooling:

If you don't have access to a Windows machine, you can probably use free VMs from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/ for testing.

But, of course, it's up to you whether you want to try that or leave to someone else with "proper" Windows machine :)

Ah, I don't think I can run those windows VMs locally either... anyhow, I'm probably the worst person for windows-specific issues as I would need to figure out basics like getting cmake and such, it's been a very long time since I did windows development.
