Ruby on rails stack level too deep

Question

Consider following model:

class Category < ActiveRecord::Base
    # nothing in the model
end

>> rails c

>> Category.all     # works fine

But when I do as below, it throws the error stack level too deep :

>> Category.order("updated_at DESC") # you should assume syntax is right

I am having this error after upgrading ruby to 1.9.3 from 1.8.7 and rails to 3.2.0 from 3.0.4. It was working fine before I upgraded. There was no code change at all, only versions are upgraded.

However I have another project on my machine with old versions and I'm facing no error there.

Apparently it looks like problem is because of upgraded versions but not sure, I have read many threads on stackoverflow but did not get satisfactory answer.

Please help I have already spent considerable time on fixing this issue with no success.

Answer 1

Try to increase the stack size with the ulimit command. Maybe it's just a bit on the small side.
