Description

I didn't remember changes related to this, however the url-loader fails suddenly with happypack. Following is my current webpack config：

plugins: [
 new HappyPack({
      id: 'font',
      threads: 4,
      loaders: [ 'url-loader?limit=200000&mimetype=application/font-woff' ]
    }),
],
module: {
  rules: [
     {
        test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/,
        loader: 'happypack/loader?id=font'
     }
]
}

And here is how I use it,

@font-face {
  font-family: 'FontAwesome';
  src: url('../fonts/fontawesome-webfont.woff?v=4.7.0') format('woff');
  font-weight: normal;
  font-style: normal;
}

result is, it doesn't work and give me warnings

Failed to decode downloaded font OTS parsing error: incorrect file size in WOFF header

Any help ?

Research direction
Investigate the interaction between HappyPack and url loader by examining HappyPack's loader pipeline implementation (likely in source files like lib/HappyPlugin.js or lib/ThreadPool.js). Reproduce the issue with the provided webpack config and a sample font file. Check if the issue is related to HappyPack's serialization of loader options or the worker's ability to decode fonts properly. Review existing comments on this issue for any additional clues.
