I'm seeing the same thing:

/usr/lib64/ruby/1.8/erb.rb:535: [BUG] rb_gc_mark(): unknown data type 0x18(0x12f2a40) non object
ruby 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux]

[Comment 3 Hans de Graaff 2010-01-23 09:09:57 UTC]

Reproducer: ruby -Ilib -rubygems /usr/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb test/haml_test.rb 

The segmentation fault happens deep in the garbage_collect code triggered by an eval. The following code is enough to cause the segmentation fault:

require File.dirname(__FILE__) + '/helper'
require 'haml'

class HAMLTest < Test::Unit::TestCase
   def haml_app(&block)
   end
end

[Comment 4 Hans de Graaff 2010-08-08 14:11:25 UTC]

Not fixed yet in haml-3.0.16.

[Comment 5 Hans de Graaff 2011-07-19 04:55:40 UTC]

This appears to be fixed with haml 3.1.1.
