Bug #11112: Segfault on `require json` in Ruby 2.1.6
https://bugs.ruby-lang.org/issues/11112

* Author: Nathan Long
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.1.6p336 (2015-04-13 revision 50298) [x86_64-darwin13.0]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
I've just installed Ruby 2.1.6 using ruby-install. If I start `irb` and type `require "json"`, I get a segfault. I'm on OSX. I've also installed and tried this on Ruby 2.1.2-2.1.5, and 2.1.6 is the only version that segfaults.

I'm attaching the console output and the crash report from ~/Library/Logs/DiagnosticReports/ruby_2015-05-01-100546_natecomp.crash

I'd be happy to answer further questions or try things that may help in diagnosing this.
