Infinite loop when attempting to parse multi-line scalar document that is not indented (sample included)

[cspotcode]

When attempting to parse the following YAML, the parser gets into an infinite loop, neither successfully parsing nor throwing an error.

--- |
hi

I am not sure which is correct according to the YAML spec: is this an invalid YAML document? Or should it parse to the string "hi"?

What version do you use? We fixed similar bug last week

I'm using the latest version, 3.2.1. It also occurs in the online demo at http://nodeca.github.io/js-yaml/

I noticed that your code is checking if the next character in the stream is !== 0 in many places, as a sort of "end-of-stream" marker.
https://github.com/nodeca/js-yaml/blob/master/lib/js-yaml/loader.js#L856

The original PyYAML code explicitly appends this null character to the end of the input text before parsing.
http://pyyaml.org/browser/pyyaml/trunk/lib/yaml/reader.py#L75

Perhaps that's the problem? In JS when you str.charCodeAt(str.length) you get NaN, not 0.

EDIT: Nevermind, I now see where you're appending the null character in js-yaml.
