Test app
Crashing from bad codegen, uses wrong registers passing arguments.
Test calls a static function and a virtual function. Static function works as
expected, virtual call crashes.
Open the project in VS2015 (others may work) and build + run.
Place a breakpoint in the virtual `addUser`function and notice that it didn't
receive its argument correctly, and also fails to return its result correct.
Static version of the function calls properly.
