Unfortunately, a fatal error has occurred. Please see the Bundler 
troubleshooting documentation at http://bit.ly/bundler-issues. Thanks!

I don't think this is a Rails issue. Can be in Ruby, Psych or bundler. But I didn't see anything related to rails in this stacktrace.

[jroes]

@rafaelfranca was thinking it might be the actual YAML file being parsed itself, perhaps?

[rafaelfranca]

The YAML file being parsed is the Rubygems specification. It is still not related with Rails. But I think we had this issue yesterday. I'll investigate

[rafaelfranca]

@jroes this is a bundler issues fixed here rubygems/bundler@d1b6ced

I don't know when the bundle guys will do one release with this fix.

Thank you for reporting.

[carlosantoniodasilva]

This is a bundler issue, it has been fixed in bundler a few days ago: rubygems/bundler@d1b6ced

[jroes]

Ah, thanks! Sorry for the misplaced report.
