This is a reduced code. Does not compile with released DMD or with github snapshot. Strangely it compiles without any error if the opCast operation is commented out. Note that the opCast operation casts to frop, which is totally unrelated.

struct Bar {
  Foo foo;
  alias foo this;
  string toString() {
    return "Bar";
  }
}

struct Frop {}

struct Foo {
  int n = 0;
  alias n this;
  T opCast (T) () if (is(T == Frop))
  {
    return Frop();
  }
  string toString() {
    return "Foo";
  }
}

void main() {
  import std.stdio;
  Foo foo;
  writeln(foo);            // no issues
  Bar bar;
  // Compiles if either the alias or opCast in Foo are commented out
  writeln(bar);            // does not compile -- should just print "Bar"
}
