A sample code that reproduce the bug

In the attached sample the compiler produce an error like this:

Test.cs(27,27): Error CS0314: The type `MoreSpecialized' cannot be used as type parameter `Specialization' in the generic type or method `Test.A<Abstraction>.For<Specialization>()'. There is no boxing or type parameter conversion from `MoreSpecialized' to `Abstraction' (CS0314)

This is wrong becouse of the constraints in A.For and in B declaration.
