Please create reproduction test repo, we have a lot of tests and everything is fine

[Shashikant-Kew]

Yes but there was no change which would cause it in our repo. We retested reverting all change. Only when we remove plugin it works. Earlier it was fine. No issue. Only after 17/18 July It started giving errors.

Please create reprducible test repo, I can't help you without more information

Hi.

@Shashikant-Kew Are you using package-lock files? If not, then your dependencies may get unexpectedly updated.

I am analyzing an issue with memory leaks that started happening when we moved our project from webpack 4 to webpack 5.

I see terser-webpack-plugin specifies any version of uglify-js supported:

    "node_modules/terser-webpack-plugin": {
      "version": "5.3.10",
      "resolved": "https://registry.npmjs.org/terser-webpack-plugin/-/terser-webpack-plugin-5.3.10.tgz",
      "integrity": "sha512-BKFPWlPDndPs+NGGCr1U59t0XScL5317Y0UReNrHaw9/FwhPENlq6bfgs+4yPfyP51vqC1bQ4rp1EfXW5ZSH9w==",
      "dev": true,
      "license": "MIT",
      "dependencies": {
        "@jridgewell/trace-mapping": "^0.3.20",
        "jest-worker": "^27.4.5",
        "schema-utils": "^3.1.1",
        "serialize-javascript": "^6.0.1",
        "terser": "^5.26.0"
      },
      "engines": {
        "node": ">= 10.13.0"
      },
      "funding": {
        "type": "opencollective",
        "url": "https://opencollective.com/webpack"
      },
      "peerDependencies": {
        "webpack": "^5.1.0"
      },
      "peerDependenciesMeta": {
        "@swc/core": {
          "optional": true
        },
        "esbuild": {
          "optional": true
        },
        "uglify-js": {
          "optional": true
        }
      }
    },

My project does run. We have this version installed:

    "uglify-js": {
      "version": "3.8.0",
      "resolved": "https://registry.npmjs.org/uglify-js/-/uglify-js-3.8.0.tgz",
      "integrity": "sha512-ugNSTT8ierCsDHso2jkBHXYrU8Y5/fY2ZUprfrJUiD7YpuFvV4jODLFmb3h4btQjqr5Nh4TX4XtgDfCU1WdioQ==",
      "requires": {
        "commander": "~2.20.3",
        "source-map": "~0.6.1"
      }
    },

I'll be writing if I find out more. This may be a clue where to start: https://github.com/mishoo/UglifyJS/releases

Jul 17 v3.19.0 very suspicious!

Jun 10 v3.18.0 could work?

Oct 23, 2022 v3.17.4 I think the most stable, but untested.

Kind regards. Thank you.
