Description

Recently upgraded rails application from ruby-2.0.0-p195 to ruby-2.0.0-p247 and seeing frequent segmentation faults now when rails action-4.0.0 calls the inspect method which loops through all the variables.

(full crash.log attached)

Not quite sure how to reproduce, other than letting it run in production until it hits this segfault. Right now, restarting application whenever this happens but impacts stability.
