test case

Just compile and run the attached test case. The missing implementation of
{get,set}_RealObject leads to the crash.

Actual result:
Segfault (see below) when calling Activator.CreateInstance

Expected result:
TypeLoadException when calling TypeBulder.CreateType (that's what .NET does)



======
no implementation for interface method IActivationProxy::get_RealObject() in
class SomeNS.SomeClass
METHOD .ctor()
