When you install custom ruby versions using a tool like ruby-build you might run into address space occupied problems.
After successfully installing ruby 2.0.0-p247 in cygwin with ruby-build as a rbenv plugin. I was getting weird child_info_fork::abort: errors that caused my call to gem install bundler to fail.
The error messages looked like this:
child_info_fork::abort: address space needed by '...' (...) is already occupied
I found this mailing list entry that included a rubyrebase script and a post describing a solution for rvm which was similiar to this.
Since these solutions lacked a single script that could be executed using ash I have created my own. You have to run the script using
ash -c '/path/to/rubyrebase'
Make sure you have closed all cygwin processes.
