json 1.8.3: json/pure fails generating Fixnum

[atombrenner]

The following snippet raises an exception when generating to_json with the pure parser.

require 'json/pure'
JSON('{"test": 5}').to_json

The C parser works like expected. If you change 5 to 5.1 it works again. Seems to be a wrong type check inside the pure generator.

I looked into generator.rb and couldn't find any kind of type check. So I got back to my code and found out that it required 'aws-sdk' which required 'json'. So to reproduce the issue on irb you need to do this:

Tuxedo:~$ irb
irb(main):001:0> require 'json'
=> true
irb(main):002:0> require 'json/pure'
=> true
irb(main):003:0> JSON('{"test": 5}').to_json

5.1

Sorry for the late feedback.

This is fixed in 2.3.0 and can be closed.
