----------------------------------------
Hi,

Whenever I run a ruby file that has a prompt, I get the a bug segmentation fault. I'm using cmder, which is a console emulator for windows. I can run the files just fine if I use the standard cmd or another console emulator.

My environment:
Windows 7 ultimate.
rails 4.1.6
