*** glibc detected *** ruby: malloc(): memory corruption:


hello

I have been experiencing some problems with my rails site, especially eith rmagick.

My images uploaded are wrong, so I thought I would test my rmagick app with a bit of ruby code
Code:
#!/usr/bin/env ruby -wKU

    # Test if rmagick is working properly or not.
    # When run, this file creates a image file 'path.gif' in the same directory.

    # the sample code is from http://rmagick.rubyforge.org/portfolio3.html

    require 'rubygems'
    require 'RMagick'

    canvas = Magick::Image.new(240, 300,
                  Magick::HatchFill.new('white','lightcyan2'))
    gc = Magick::Draw.new

    gc.fill('red')
    gc.stroke('blue')
    gc.stroke_width(2)
    gc.path('M120,150 h-75 a75,75 0 1, 0 75,-75 z')
    gc.fill('yellow')
    gc.path('M108.5,138.5 v-75 a75,75 0 0,0 -75,75 z')
    gc.draw(canvas)

    canvas.write('path.gif')
which should generate a nice little gif.

but when I run it i get an error: any ideas? i have't seen anything like this before...
