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. ---Files-------------------------------- crash_console_output.txt (10.1 KB) ruby_2015-05-01-100546_natecomp.crash (15.5 KB) -- https://bugs.ruby-lang.org/
