Consider the following incorrect model:

abstract LogicalBus : LogicalBus
    xor type
        CAN
        LIN

bus1 : LogicalBus

The compiler will output the following:

clafer -m choco debug.cfr 
All clafers: 5 | Abstract: 1 | Concrete: 4 | Reference: 0
Constraints: 0
Goals: 0

The Clafer process then hangs and does not complete. This type of inheritance should not be allowed and should throw an compile error.

The same happens for a model:

abstract A : B
abstract B : A
