Error: Cannot resolve callback 1 when opening multiple pdfs

Link to PDF file (or attach file here):

pdf-sample.pdf compressed.tracemonkey-pldi-09.pdf

Configuration:

• Web browser and its version: Chrome 56.0.2924.87
• Operating system and its version: OSX 10.11.6
• PDF.js version: pdfjs-dist 1.7.414
• Is an extension: No

Using following React component:

import React, { Component } from 'react';
import PDFJS from 'pdfjs-dist/webpack';

class App extends Component {
  constructor() {
    super();
    this.state = {pdfs: []};
    this.handleInputChange = this.handleInputChange.bind(this);
  }

  handleInputChange(event) {
    const file = event.target.files[0];
    const reader = new FileReader();
    const self = this;
    reader.onload = function() {
      const typedArray = new Uint8Array(this.result);
      PDFJS.getDocument(typedArray).then(pdf => {
        self.setState({pdfs: self.state.pdfs.concat(pdf)});
      });
    };
    reader.readAsArrayBuffer(file);
  }

  render() {
    return (
      <div>
        <input type="file" onChange={this.handleInputChange}/>
        <ul>
          {this.state.pdfs.map((pdf, i) => <li key={i}>{pdf.numPages}</li>)}
        </ul>
      </div>
    );
  }
}

Steps to reproduce the problem:

1. Upload first attached PDF
2. Upload second attached PDF

What is the expected behavior? Both PDFs’ page counts are printed:

What went wrong? The expected behavior occurs, but PDF.js throws the following error when a second PDF is opened, and will throw the error again whenever a new PDF is opened:

Error: Cannot resolve callback 1
pdf.js:340     at error (http://localhost:3000/static/js/bundle.js:33026:18)
    at MessageHandler.messageHandlerComObjOnMessage (http://localhost:3000/static/js/bundle.js:33732:10)

(specifically, from line https://github.com/mozilla/pdf.js/blob/59392fd5442d819879dc7ec0a0a8ce9a2fbd2f71/src/shared/util.js#L1291)

This appears unrelated to the contents of the PDFs, this occurs with any sequence of multiple PDFs I’ve tried other than opening the same file twice.

If I call pdf.destroy() on the already-open PDF before opening another, this does not occur.

@yurydelendik I published a complete minimal project here: https://github.com/gdaolewe/webpack-pdfjs-repro

@rvinay88 @mattnetto can you publish complete project (instead of snippets of code)?
