- SR-1980 Emit multiple vtable entries for overrides that change calling convention
Issue Description:
See enclosed project:
The property "rect" is declared optional in one file, and non-optional in an override in a subclass. This causes the compiler to crash. I realize this is not legal, but it took me a while to track it down since the compiler crashes before showing the error.
