terser-webpack-plugin: Terser@4.1.5 broken

I have traced an error coming from react-styleguidist that use this plugin.

The terser@4.3.4 is the last working version, between 4.3.5 and 4.3.8 I got all my build broken with Maximum call stack size

• https://github.com/styleguidist/react-styleguidist/issues/1441

Could we please fix terser while waiting they release a fix and publish a new version of this plugin with fixed terser@4.3.4?

Thanks
