As far as I can see this is a feature, not a bug.  If you wanted
do_stuff1() to insist on using a.c's test_proto(), then make it use a
different function and make it a private or nomask function so nobody
inheriting it can redefine it.  All you did now was provide a default
implementation for test_proto() which you override in b.c.

Did I miss something?
