Summary: crash: inheritance and generic prototypes 
Target Milestone: Lisaac 0.4
Category: Lisaac Compiler


Initial Comment:
The lisaac compiler crash on a call on NULL.
Included a testcase and a patch (included in the branch stable) to raise an error instead of crashing.

The problem happens when a prototype with no generic parameters inherit from a prototype with generic parameters. Any call on the parent prototype that happen to involve a generic parameter crash because the compiler can't find the real type for the type parameter.

The problem is that ITM_TYPE_PARAMETER.to_run_for sometimes returns NULL
