Thought I'd post this, let me know if I can help with more info.

I've experienced it in a number of different places. No segfaults occurring when debugger is not used.

Is this reproduced with byebug instead of debugger?

On MacOS X, a crash log file under ~/Library/Logs/DiagnosticReports is important.

No, using byebug (2.7.0) in the same way does not reproduce the bug (thanks for pointing this gem out btw).

This is also happening to me when using debugger
Ruby 2.1.0, Mavericks 10.9.3 (Build 13D12), rails 4.0.3, debugger 1.6.6, rspec-rails 2.14.1

On debugger gem repository:

• https://github.com/cldwalker/debugger/issues/114 - Same segfault
• https://github.com/cldwalker/debugger/issues/47 - Ruby 2.0.0 is not officially supported by debugger gem
• https://github.com/cldwalker/debugger/issues/69 - Somebody is trying to help the maintainer to port the code for 2.0.0 compatibility...
• https://github.com/cldwalker/debugger/issues/89#issuecomment-26330015 - Because the maintainer is facing some problems in having time to do it.
• https://github.com/deivid-rodriguez/byebug - Some people are using byebug instead.
