Color is causing issue to all my documentation #163

I am using Webpack 4.41.0 and I have issue with production build of documentations.

I got all my documentation production build broken for some reason.

Example: https://rollup-umd.github.io/test/

Error: RangeError: Maximum call stack size exceeded

I haven't change anything in my source code. It just happen to be broken.

I can't remove UglifyJS plugin because react-styleguidist forbid it.

Current behavior

After running npm run styleguide:build, I have:

bundle.ebc589be.js:65 Uncaught RangeError: Maximum call stack size exceeded
    at e (bundle.ebc589be.js:65)
    at e (bundle.ebc589be.js:65)
   ...

To reproduce

• Example: https://rollup-umd.github.io/test
• Local Reproduction:

git clone git@github.com:rollup-umd/test.git
cd test
npm i
npm run styleguide:build
npm i -g serve
serve public
# open chrome and http://localhost:5000

Expected behavior

• Work as in npm run styleguide.

Related information

It was working 24h ago, since then, I have not change anything in all my sources codes.

All my production build in all my projects are down.

I believe (unless I am wrong but to me it is the only valid reason): the dep tree as changed.

For those who ask why I don't have a lock file: It is because we do not use package-lock.json in distributed modules, because lock file are for application.

• Does anybody have an idea of what changes recently?
• Is there a way I can trace and find what cause all my documentations to be broken?

Debugging

I just added a breakpoint in the minified code and went up the trace, and it happen in a library called color, exactly here.

This file as not been changed since June, and the library where I use it here as also not changed since February.

Something must have change somewhere in the prod build and webpack is in charge of that.

It work on codepen.io : https://codesandbox.io/embed/peaceful-bouman-53ycx

This is the debugger showing me color:

I am not an expert but is there a way to fix that in color code ?
