opening a lot of files segfaults on windows

[not-nullptr]

How can we reproduce the crash?

https://github.com/not-nullptr/bun-fs-crash

the script opens n workers, where n is the amount of cpu cores you have, and then attempts to read sample.txt 1,000,000 times distributed across those workers. this works under wsl, but crashes on windows.

Relevant log output
