memory leak when instance is created inside a function.

Hi, I just noticed that when you create debug instance in a function, it is starting to leak the memory without freeing. Here’s how you can reproduce it:

const debug = require('debug');

const loop = () => {
  const d = debug('namespace:that:i:want:for:this:function');
  d('hello world');
  setImmediate(loop);
};

loop();

If you run this and look at memory, it is leaking a lot without freeing them. also does not matter if I set environment to DEBUG=* or not, it still leaks. Any thoughts?

EDIT: tested on 3.1.1 and 4.1.1 as well (had 3.1.1 version and then I upgraded to latest one to check if it was fixed).

EDIT2: using node version 10.13 and Windows 10 x64.

Hi @brandonros, I’m currently dealing with moving into my new apartment across the planet, a full time job, a new full time job on the way, and some heavy family issues.

Nobody is paying me to do any of this.

I have been primarily mobile for the last 3 weeks. I have little problem responding to issues on GH, but am relatively incapable of doing much coding.

I’m not sorry my schedule doesn’t revolve around you, sir.
