If I change @original_attributes ||= {} to @original_attributes || {}
in lib/dm-core/resource.rb, I no longer get this error - so it is
definitly the problem that somehow @original_attributes is getting
frozen.
I cannot find anywhere in dm-core that would cause this. Does anyone
more familiar with this know why this would happen?
For now, I am going with that small change which should be fine
(should), but I don't like the idea that the instance variable is
being frozen when I don't see a #freeze method happening anywhere near
there. I might have to override the freeze method and log when it is
used or something.
