Webpack out of memory error with postcss-loader 7.2.x

Bug report

Every production webpack build is failing with an out of memory error once I update to postcss-loader 7.2.x. As soon as I downgrade back to 7.1.x, it works again.

Actual Behavior

Expected Behavior

It should not be throwing out of memory errors and core dumps.

How Do We Reproduce?

Run a webpack build with the latest postcss-loader? All the webpack builds in our private repos fail with the latest version of postcss-loader, but I can't post those configurations publicly.

Sorry, I can't fix it here, looks like a bug on ts-node side and jest
