Bug 19132 – Attempting to override an alias crashes DMD

Attempting to compile the following code results in an Access Violation with DMD 2.081.1: class Base { void test() { } alias hello = test; } class Derived : Base { override void hello() { } } Expected result: Error: function `app.Derived.hello` does not override any function. Special casing attempts to override an alias alternatively could produce an error along the lines of "function `app.Derived.hello` cannot override an alias." As a note, moving `alias hello = test` to Derived produces the expected result.
