Bug 23151 – ICE: core.exception.AssertError@src/dmd/aggregate.d(678): Assertion failure

From: https://forum.dlang.org/post/[email protected] ```d interface I { void intfunc(int x); } auto makeBaseObj() { int realPrivateX; class Base : I { private int modulePrivateX; int publicX; override void intfunc(int x) { realPrivateX++; // expected OK } } return new Base; } auto makeDerivedObj() { int realPrivateY; class Derived : typeof(makeBaseObj()) { private int modulePrivateY; int publicY; override void intfunc(int x) { realPrivateX++; // expected NG modulePrivateX++; } } return new Derived; } ``` Output: /tmp/test.d(20): Error: class `test.makeDerivedObj.Derived` is nested within `makeDerivedObj`, but super class `Base` is nested within `makeBaseObj` --- ERROR: This is a compiler bug.
