JavaScript heap out of memory during rum my loader via custom-webpack

[zxs2162]

Describe the Bug

After upgraded to 15.0.0 (also Angular 15..1.3)

My build failed.

Then during building: (5 GB memory assigned)
12:14:44 + npm link webpack
12:14:49 /usr/local/bin/webpack -> /usr/local/lib/node_modules/webpack/bin/webpack.js
12:14:49 + [email protected]
...

12:14:49 + ng build app --configuration production --named-chunks=true
12:14:51 - Generating browser application bundles (phase: setup)...

But everything works well before custom-webpack upgrading to 15(previous version is 13.x)

And, I increase memory to 16GB, build can proceed successfully.

Minimal Reproduction

"builder": "@angular-builders/custom-webpack:browser", ... "customWebpackConfig": { "path": "./my-custom-webpack.config.js", "replaceDuplicatePlugins": true }, - my-custom-webpack.config.js ： const path = require('path');

module.exports = {
resolveLoader: {
modules: ['node_modules', './scripts/'],
},
module: {
rules: [
{
test: /.scss$/,
exclude: [/theme.scss$/, /styles.scss$/],
use: [
{
loader: path.resolve('./scripts/my-rtl-webpack-loader.js'),
},
{
loader: 'postcss-loader',
options: {
postcssOptions: {
ident: 'postcss',
syntax: 'postcss-scss',
plugins: [require('postcss-rtl'), require('autoprefixer')],
},
},
},
{ loader: 'sass-loader' },
],
},
],
},
};


• my-rtl-webpack-loader.js

Attention, to minimize the impact, my-rtl-webpack-loader.js will d nothing there!!!

const loaderUtils = require('loader-utils');

module.exports = function (source) {
this.callback(null, source);
};


Expected Behavior

Build should be working with 15.
