Fixing thi bug is difficult for me.

DMD internally behavior is...
1.Elaborate constructor returns this reference internally.
  -> see CtorDeclaration::semantic()
2.Elaborate constructor call T(args) is translated like (T __ctmp,
__ctmp.__ctor(args)) and __ctmp.__ctor returns ref T.
  -> see CallExp::semantic

Trivial fix patch is follwing, but this causes copying value.
