If you set the parent type of a built in type (say, /datum) to one of their children (say, /atom), the compiler will lock up and use 100% of a CPU core.
Code Snippet (if applicable) to Reproduce Problem:
/datum
parent_type = /atom
Expected Results:
Some sort of compiler error like what you get when you do this for your own types.
Actual Results:
The compiler locks up and consumes 100% of a CPU core.
Does the problem occur:
Every time? Or how often? Every time
On other computers? Yes
