"options: error: AccessDenied" race on Windows with build options post #14647

[scheibo]

Zig Version

0.11.0-dev.2247+38ee46dda

Steps to Reproduce and Observed Behavior

I'm assuming Windows needs something similar to the solution for macOS from #15006

$ git clone https://github.com/pkmn/engine.git
$ zig -Dshowdown=false tools -p build

Note: this doesn't seem to fail consistently - it has failed on the GitHub CI on 1/4 windows runs the last two times ive pushed and then when the job is retried it succeeds. https://github.com/pkmn/engine/actions/runs/4506104662/jobs/7932535027

options: error: unable to rename options from 'D:\a\engine\engine\zig-cache\tmp\67ec2197bc57191a\options.zig' to 'D:\a\engine\engine\zig-cache\c\fb49e8bc5ba2181c23673c24abe88e66\options.zig': AccessDenied

Expected Behavior

No error :)

#8362 possibly related?

This is possibly fixed - I haven't seen it repro after 0.11.0-dev.3132 (possible #15641 fixed this?). If i see this crop up again I will reopen/try to get a more usable reproduction.

[scheibo]

OK so this still repros (though less frequently?) https://github.com/pkmn/engine/actions/runs/5052518703/jobs/9065449621

Don't really have a nice friendly minimal set up for this beyond the initial description. nor do i know if the fact that is seems to be consistently failing on the build options package is relevant

Windows-specific issue is probably related to #14978
