Hi all! I made a simple project with vue-cli(which use vue-template-compiler@2.1.0), and found this error:

Cannot read property 'text' of undefined
    at Object.chars (eval at <anonymous> (app.js:969), <anonymous>:1385:65)
    at parseHTML (eval at <anonymous> (app.js:969), <anonymous>:537:17)
    at parse (eval at <anonymous> (app.js:969), <anonymous>:1203:3)
    at compile$2 (eval at <anonymous> (app.js:969), <anonymous>:2283:13)
    at compile$1 (eval at <anonymous> (app.js:969), <anonymous>:5739:10)
    at Object.compile$$1 [as compile] (eval at <anonymous> (app.js:969), <anonymous>:5931:18)
    at VueComponent.mounted (eval at <anonymous> (app.js:800), <anonymous>:16:22)
    at callHook (eval at <anonymous> (app.js:735), <anonymous>:2754:19)
    at Object.insert (eval at <anonymous> (app.js:735), <anonymous>:1765:5)
    at invokeInsertHook (eval at <anonymous> (app.js:735), <anonymous>:4474:28)

Here is the case:

const compiler = require('vue-template-compiler');
compiler.compile('<pre>\n<span> <span></span></span>\n</pre>');

or directely write in template of a .vue file:

<template>
   <pre>
      <span> <span></span></span>
   </pre>
</template>

This errors occurs in vue-template-compiler/build.js :1385:65

else if (text !== ' ' || children[children.length - 1].text !== ' ') {
      currentParent.children.push({
            type: 3,
            text: text
      });
 }

In this case children is an empty array, so it happens.

Thank you.
