I don't recall why it doesn't find the common type. But what it does do is use the last element to deduce the type, so there are two ways to make this work.

auto b = [new B, cast(A) new C];
auto b = [new B, new C, new A];

What I don't really like is that it can't be fixed with:

A[] b = [new B, new C];
