Description

Any input to the irb REPL seems to crash it immediately. I haven't had any problems with pry or ruby itself--it seems to be just irb. I'm running Ruby 2.2.2p95 on Ubuntu 15.04. I'm using rbenv and ruby 2.2.1p85 (2015-02-26 revision 49769) seems to have this problem as well, but the irb in ruby 2.1.2p95 (2014-05-08) seems fine.
