ActiveSupport JSON encoding, default JSON gem and SystemStackError

[jayeff]

Hi,

after I updated to v4.6.1 I can no longer encode a Tweet to JSON with as_json / to_json. When I try to encode the tweet with a user I get a SystemStackError: stack level too deep.

Here's a gist: https://gist.github.com/jayeff/5196230 / this problem still exists on current HEAD
I'm running ruby 1.9.3-p374, OS X 10.8.2

I dug a bit into this. Bisecting says that it stopped working with ff4f2da. The problem is that when I encode the tweet, this encodes the referenced User, who references the tweet (user.status), this tweet again references the User, etc.
#364 discusses this as well. Both changes do not solve the describe problem.

Yep, seeing this as well.

Thanks for reporting this. I'll revert ff4f2da and release a new version of the gem.

Released version 4.6.2, which should resolve this issue.

[jayeff]

It did. Thanks.

@sferik Thanks from me too.
