Yes I am.

As in directly calling operator<< ?
Yes, operator function calls and inferior function calls take separate 
code paths. I was going to look into unifying those after I got cout to 
work.

In the case of cout << 1 I would add:

 * debug info is not loaded without
   set debug-file-directory /usr/lib/debug
 * operators which are members of the namespace
   not the class are not found.
 * the namespace of arguments (like cout) are not easy to figure out
   during lookup.
