thank you for the bug report @vjpr !

it looks like esm has problems with symlinks.

@jdalton in order for the repro to succeed (or, should I say successfully fail), it is paramount to install the dependencies as the issue title suggests with pnpm.

https://pnpm.js.org/docs/en/installation.html

npm i -g pnpm
pnpm i
node -r esm main.mjs

Thanks @vjpr! _(and @dnalborczyk!)_

The issue was around resolving hard-links.
I'll try to come up with a test for that.

Update:

v3.0.73 is released :tada:
