This patch seems a bit more generic and solved a similar issue for me. It also
works for your code:

Index: declaration.c

--- declaration.c    (revision 576)

     {   error("recursive alias declaration");
         aliassym = new TypedefDeclaration(loc, ident, Type::terror, NULL);
     }
+    else if (!aliassym && scope)
+        semantic(scope);
+
     Dsymbol *s = aliassym ? aliassym->toAlias() : this;
     return s;
 }
