rbx-with-pry-doc-test

Stripped all of the Rails app out to make the minimal testcase.

Steps to reproduce

1. This assumes you have RVM installed, and it's invoked to create a new minimal gemset that includes 'bundler'.
2. run bundle install (see 'initial-gem-list.txt' for my system state)
3. run pry; this starts normally for me
4. uncomment 'pry-doc' in Gemfile
5. run bundle install (see 'with-pry-doc-gem-list.txt')
6. run pry

Error

At step 6 above, I get an extremely long (~6k lines) repetitive backtrace starting with:

gem install awesome_print # <-- highly recommended An exception occurred running /Users/hassan/.rvm/gems/rbx-head@pry-doc-test/bin/ruby_noexec_wrapper SystemStackError (SystemStackError)
