Subject: [ruby-core:61956] [ruby-trunk - Bug #9594] Segfault in 2.1.1 follows cont from debugger (Rails 4.0.3, debugger 1.6.6, rspec, os x mavericks 1.9.2)

Issue #9594 has been updated by Abinoam P. Marques Jr..


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.

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.
