Description

Explicit overrides of an interface are not handled consistently in all situations. Specifically, a C3241 error can occur in some function signatures but not others. The following code works fine:


class IFoo
{
public:
	virtual bool foo() = 0;
};

class Bar : public IFoo
{
public:
	bool IFoo::foo() { return true; }
};


However, if the function signature were changed to `bool foo() const` an error C3241 occurs, claiming that the function was not introduced by IFoo. This error is incorrect.

Hi:
    A fix for this issue has been checked into the compiler sources. The fix should show up in the next release of Visual C++.
