rmagick leads to server shutdown

Question

everyone! I was following Railscasts episode #253, using CarrierWave to do image upload.

Everything was fine to display the original image, even though the image looked quite big in the browser.

I strictly followed Ryan Bates' instructions. But, when I tried to resize the image using rmagick and press upload button, I always got server shutdown. I am using rmagick 2.13.1 And I followed this blog's instruction to install homebrew, and imagemagick on my mac.

The error message is shown below.
