Version

v16.16.0 (also main branch at this moment)

Platform

Linux pop-os 5.19.0-76051900-generic #202207312230166078056622.04~9d60db1 SMP PREEMPT_DYNAMIC Thu A x86_64 x86_64 x86_64 GNU/Linux

No response

What steps will reproduce the bug?

By running code like this:

process.binding('uv').errname(0)
process.binding('uv').errname(1)
process.binding('uv').errname()

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

Always

What is the expected behavior?

It should not crash, it could return undefined or do the libuv call

What do you see instead?

> process.binding('uv').errname(0)
node[742775]: ../src/uv.cc:75:void node::uv::ErrName(const v8::FunctionCallbackInfo<v8::Value>&): Assertion `(err) < (0)' failed.
