Janus,  

thanks for your hard work!
I'm sorry to post another bug / possibly further evidence of the same bug. 

When the non_overridable function is part of a generic set, and the generic
binding is called (either from the same or from an inherited class, doesn't
matter), I get internal compiler error (segfault) with gcc 5.3.0 and 6.1.0.

I have attached another minimal test to show the compiler's behavior. 
Maybe your fix also fixes this?

Best, 
Federico
