JavaScript heap out of memory

[quentincaffeino]

How do we reproduce the issue?

We'll likely need to know:

1. Your Rollup configuration.

import svelte from 'rollup-plugin-svelte'
import resolve from '@rollup/plugin-node-resolve'
import commonjs from '@rollup/plugin-commonjs'

import babel from 'rollup-plugin-babel'
import visualizer from 'rollup-plugin-visualizer';
import compiler from '@ampproject/rollup-plugin-closure-compiler';
import rimraf from 'rimraf'

rimraf('./public/js', {}, () => console.log('removed public/js'))
require('dotenv').config();

3. Error logs when this plugin is removed from your Rollup configuration.

When I remove compiler logs are fine.

[tarsisexistence]

I also have this in a project where there are a lot of SCSS imports, with a long tree dependency
when I turn off almost all SCSS imports it compiles fine.

I didn't come up with an idea of what is it...

[quentincaffeino]

What closure compiler has to do with CSS imports?

[tarsisexistence]

I can’t say that I am good at the closure compiler. In this regard, I am a complete beginner

but it seems to me that the problem is related to the circular dependency

usually, if I got similar errors, they were always related to the circular dependency and most likely my problem is precisely this

[kristoferbaxter]

Apologies for delays looking into this. I’m out on paternity leave, but will try to address as soon as I can.

[quentincaffeino]

No worries. Thanks for your time.

Also I tried some more: If I run compiler in dev environment it runs fine. Even in advanced mode. Then it has undefined regeneratorRuntime but that's probably an issue with my babel setup.
