Hi.

I ran into a segmentation fault, the reproduction steps are here:

$ git clone https://github.com/r-obert/pry-plusplus.git
$ cd pry-plusplus
$ git checkout edf3496f425ef2512431a79b72a2a5fd930b2fcf
$ gem install bundler --no-rdoc --no-ri
$ bundle install
$ rake pry # or: ruby -Ilib bin/pry
pry(main)> _pry_.h.deprecate_method! Object.methods.map{|m| Object.method(m) }, "everything is deprecated"
zsh: segmentation fault rake pry

Sorry, I have not reduced further. Could this be an exception instead, so I can see what is wrong? Thanks.

JRuby provides a little more useful information:

[1] pry(main)> _pry_.h.deprecate_method! Object.methods.map{|m| Object.method(m) }, "everything is deprecated"
DEPRECATED: everything is deprecated
.. Called from ../code/rb/pry-plusplus/lib/pry/deprecate.rb:34:in `define_method'

Hi.

This is fixed on 2.5.0:

2] pry(main)> _pry_.h.deprecate_method! Object.methods.map{|m| Object.method(m) }, "everything is deprecated"
Traceback (most recent call last):
	5405: from bin/pry:12:in `<main>'
	5404: from ../code/rb/pry-plusplus/lib/pry/cli.rb:116:in `start'
	5403: from ..code/rb/pry-plusplus/lib/pry/pry_class.rb:192:in `start'
        ..
	 ... 5393 levels...

$ ruby -v
ruby 2.5.0dev (2017-09-05 trunk 59751) [x86_64-darwin15]

But my instructions do not work on 2.5.0, since bundle install does not work:

$ bundle install
../ruby-head/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_gem.rb:67:in `synchronize': deadlock; recursive locking (ThreadError)

So, $ gem install coderay method_source --no-rdoc --no-ri would have to be used first.

Are there plans for a release before December?
2.4 seems a little buggy. I've hit a different segfault too, that has since been fixed on trunk.

Please mark this as closed, as I seem unable to. Thanks.
