This is a really strange one. Latest ruby stable, rails 2.0.2, debian sid. About a dozen plugins installed which makes it more difficult to track down...
In routes.rb I have the following:
map.resources :profiles, :controller => :user_profiles
So I'm using profile_path(user_obj) in my views. And I'm using acts_as_commentable.
profile_path(current_user), where current_user is from acts_as_authenticated works fine. But when I get a user object from Model.comments.users, and pass that to profile_path, immediate segfault. Using ruby-debug to step through a line running mongrel only confirms this is where it's bombing, I haven't been able to track it down further yet. Even more interesting is that it only segfaults the second time the code is run (second page load in the same process).
Ya so I know what to do next, but though I'd post this in case someone might have an idea where to look first.
