* Author: Pavel Lobashov

* Priority: Normal
* Assignee: Koichi Sasada
* ruby -v: 2.4
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: REQUIRED
----------------------------------------
1. Create test.rb this code
~~~ ruby
require 'rmagick'
include Magick
(0..10).each do |_|
ImageList.new('1.bmp').get_pixels(0, 0, 1600, 800).each_slice(1600).to_a
end
~~~
2. Create any 1.bmp file with dimension at least 1600*800 (Include zip file with it, extract it in directory with test.tb)
3. Install ruby 2.1.9 (via RVM for example) and run
~~~ text
ruby -v # ruby 2.1.9p490 (2016-03-30 revision 54437) [x86_64-linux]
ruby test.rb # Nothing output, all good
~~~
4. Install ruby 2.3.1 (via RVM for example) and run
~~~ text
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]
ruby test.rb # You get a big log of Segmentation failed
~~~
I issued an problem on `rmagick` issue tracker (https://github.com/rmagick/rmagick/issues/212) but there is no progress at all
So I thought since both rubies use same version of rmagick I think problem may be in ruby itself.
