As the title says,
class AA {
protected void Fun() {}
}
class BB : AA {
override void Fun() {} // should throw compile error for inconsistent accessibility.
}
AA a = new AA();
BB b = new BB();
AA upcasted = (AA)b;
a.Fun(); // compile error.
b.Fun(); // ok, instead, should throw compile error.
upcasted.Fun(); // the object is of type BB, but casted to AA, compile error.Also this code causes a crash if you put the last six lines into a non-member function. In the repro code, as you can see I put it in a member function instead, which causes no crash, if I were to remove the class, and just leave the function, the workbench crashes, all I know for now is that this is due to 'protected' modifier in the AA class.
