class A { auto foo() { return 0; } } class B : A { override auto foo() { return 5; } } The compiler crashes. It also crashes if A.foo's return type is int or B.foo's return type is int (but not if both are int, obviously). It doesn't crash if foo is not overridden.

Is it the same as bug#3042?

With my patch for bug #3042 applied, this generates: bug.d(4): Error: function ice.B.foo of type () overrides but is not covariant w ith ice.A.foo of type () So marking as duplicate. *** This issue has been marked as a duplicate of issue 3042 ***
