This is a const conversion for the generic type that is failing to diagnose.
Changing from a generic container to id seems to work.  Assignment of const
ObjectType * to a NSObject * const seems to trigger the assertion.

Stored value type does not match pointer operand type!
  store i8** %6, %1*** %objects, align 8, !tbaa !9
 %"type 0x1040351f0"**

Seems that we need a cast; %6 is most likely a call (running with master under
a debugger indicates that the store is for a call).
