nodejs / copyfile: bad address in system call argument

Hi iSH team!

Some of my nodejs apps are failing on iSH because of a bug in system call copyfile (see below).

Could somebody please help in fixing this issue in iSH?

And of course let me know if I can help in any way :-).

Thanks a lot and keep the excellent work with iSH!

Kind regards,
Maurice

** Easy steps to reproduce this bug on iSH v1.3.2 (Build 494)

echo hello >a
apk add nodejs
node -e "require('fs').copyFileSync('a','b')"

** Note

Having a non empty 'a' file is important because copying an empty file actually works

** Results on the defaut iSH alpine v3.14 with default minirootfs v3.14.3

node -e "require('fs').copyFileSync('a','b')"
internal/fs/utils.js:332
throw err;
^

** More expressive results on latest alpine v3.18 with minirootfs v3.18.2

node -e "require('fs').copyFileSync('a','b')"
node:internal/fs/utils:351

Node.js v20.3.1

** Results using previous alpine versions

echo hello >a
apk add nodejs
node -e "require('fs').copyFileSync('a','b')"

minirootfs:
- 3.0 to 3.6: no nodejs
- 3.7.3: node v8.9.3 => copyFileSync works
- 3.8.5: node v8.14.0 => copyFileSync works
- 3.9.6: node v10.19.0 => copyFileSync works
- 3.10.9: node v10.24.1 => copyFileSync works (last working version)
- 3.11.0: node v12.22.6 => copyFileSync DOES NOT WORK
- 3.11.13: node v12.22.6 => copyFileSync DOES NOT WORK
- Any other version after => copyFileSync DOES NOT WORK

** Some variations if needed

node -e "require('fs').copyFileSync('a','b')"
node -e "require('fs').copyFile('a','b',console.log)"
node -e "require('fs').promises.copyFile('a','b')"
node -e "require('fs').cpSync('a','b')"
node -e "require('fs').cp('a','b',console.log)"
node -e "require('fs').promises.cp('a','b')"
