What steps will reproduce the bug?

Shell command: node -e 'console.log(fs.BigIntStats)'

How often does it reproduce? Is there a required condition?

Always reproduces.

What is the expected behavior? Why is that the expected behavior?

I would expect this to output the usual representation of a class / constructor named BigIntStats, which is a class named in the documentation for the fs module, e.g. at https://nodejs.org/docs/latest/api/fs.html#class-fsstats under "bigint version."

(What I actually want to do is stuff like if (stats instanceof fs.BigIntStats) ....)

What do you see instead?

$ node -e 'console.log(fs.BigIntStats)'
undefined
$
