Bug What is the current behavior? yarn produces javascript heap out of memory issue when upgrading to webpack@4.20.2 particularly. I have not found it to be an issue when upgrading other packages.

further investigation shows that anything beyond 4.5.0 have this out of memory issue. I was able to successfully install webpack@4.5.0

If the current behavior is a bug, please provide the steps to reproduce.

git clone https://github.com/fobbyal/yarn-install-mem-heap-issue.git
yarn install
yarn add webpack@4.20.2

What is the expected behavior? yarn installs the webpack@4.20.2 succssfully.

Please mention your node.js, yarn and operating system version. yarn@1.10.1 node@8.10.0 on OSX and node@8.12.0 on arch linux

Contributor guide

Reproduce using `yarn add webpack@4.20.2` and monitor memory usage with `NODE OPTIONS= max old space size=8192`. Profile heap snapshots to identify the source of memory growth.
