symbol lookup error

[Goltergaul]

i can open an irb at a breakpoint but as soon as i try to exit the irb with the exit command my rails server crashes with the following error message:

/home/goltergaul/.rbenv/versions/2.1.0/bin/ruby: symbol lookup error: /home/goltergaul/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0/extensions/x86_64-linux/2.1.0-static/debugger-1.6.5/ruby_debug.so: undefined symbol: rb_vm_get_sourceline

Debugger is not compatible with ruby v2.1, please use byebug instead.

I'll be submitting a pull request to Rails to change the debugger shipped in the default gemfile as soon as I get time. The fact that they recommend ruby 2 or greater but they still have debugger in their default gemfile is misleading.

thanks for the info

Can anyone point me in the right direction to work around that issue? It seems that other people do not have this problem. What could it be?

Closing since I'm scoping debugger to just 1.9.2 and 1.9.3. For more see https://github.com/cldwalker/debugger/issues/125#issuecomment-43353446
