Description

Looks like the webpack.SourceMapDevToolPlugin causes a crash with larger repositories. Adding the plugin webpack.EvalSourceMapDevToolPlugin resolves the issue. But the bundler takes longer since SourceMapDevToolPlugin is still required by haul to resolve certain links.

Code changes to webpack config

webpackconfig.plugins.push(new EvalSourceMapDevToolPlugin({
  exclude: /node_modules\/(?!(local_package1|local_package2|local_package3).*/,
}))

Reproducible Demo

You need a lerna monorepo that is massive. That imports a lot of expensive components and maybe some that are not fully optimized for react-native.
