pbosetti/ruby-opengl — Issue #1: invoking Gl.is_available? crashes irb

I'm running ruby 1.9.3 installed from rvm on a mac running OS X 10.6.8.

Here's the dump from irb of the interaction I performed to make it crash. It's certainly reproducible on my system. I haven't tried to reproduce it on other machines.

If you contact me, I'd be happy to help diagnose the problem further.

$irb
1.9.3-p0 :001 > require 'opengl'
=> true
1.9.3-p0 :002 > Gl
=> Gl
1.9.3-p0 :003 > Gl.is_available?(2.0)
