Bug 14390 – [REG2.068a] ICE or bad "has forward references" error with circular class structure

Slight variant of issue 12984. Works in 2.067.0. Feel free to change the title to be more to the point. I can't really wrap my head around all this. --- cat > test.d << code class B {alias MyD = D!int;} class C : B { version(ice) void m() {alias MyD = D;} version(forward_references) static struct S {alias MyD = D;} } class D(T) {alias MyE = E!float;} class E(T) : D!int { void m() {new C;} } code dmd -c -o- -version=ice test.d echo "-" dmd -c -o- -version=forward_references test.d --- dmd: mangle.c:231: void Mangler::mangleFuncType(TypeFunction*, TypeFunction*, unsigned char, Type*): Assertion `0' failed. Aborted (core dumped) - test.d(5): Error: struct test.C.S has forward references ---
