This regression got introduced in dmd-2.061 (works with dmd-2.060).

$ dmd test.d
dmd: glue.c:1227: virtual unsigned int Type::totym(): Assertion `0' failed.
Aborted (core dumped)
$ cat test.d
import foo;
$ cat foo.d
struct CirBuff(T) {
  import std.traits: isArray;
  CirBuff!T opAssign(R)(R ) if(isArray!R) { }

  struct Range(U,S) {
    Range!(U,S) save() {return U;}
  }

  T[] toArray() {
    T[] ret = new T[this.length];
    return ret;
  }

  alias toArray this;

  Range!(T, T) range() {}

}

class Bar (T=int){
  CirBuff!T _bar;
}

class Once {
  Bar!Foo _foobar;
}

class Foo: Frop {}

Another interesting testcase. Class Frop is not defined, but DMD fails to catch
that. dmd-2.060 works fine.


$ ~/local/dmd-2.060/dmd2/linux/bin64/dmd -c test.d
foo.d(22): Error: undefined identifier Frop
$ cat test.d
import foo;
$ cat foo.d
struct CirBuff(T) {
  import std.traits: isArray;
  CirBuff!T opAssign(R)(R ) if(isArray!R) { }

  T[] toArray() {
    T[] ret = new T[this.length];
    return ret;
  }
  alias toArray this;
}

class Bar (T=int){
  CirBuff!T _bar;
}

class Once {
  Bar!Foo _foobar;
}

class Foo: Frop {}

Another testcase (after pulling in the pull request). DMD does not crib about
missing override for function Foo.frop. But starts doing that if "alias toArray
this" in CirBuff(T) is commented out.

struct CirBuff(T) {
  import std.traits: isArray;
  CirBuff!T opAssign(R)(R ) if(isArray!R) { }

  T[] toArray() {
    T[] ret; //  = new T[this.length];
    return ret;
  }
  alias toArray this;
}

class Bar (T=int){
  CirBuff!T _bar;
}

class Once {
  Bar!Foo _foobar;
}

class Foo: Frop {
  // override
  public int frop() {return 1;}
}

class Frop {
  public int frop() {return 0;}
}
