Maybe I'm missing some details (I will read again your message
later), but, if this is your main point, there is little doubt
that, according to the ISO standard that we are implementing,
this is right behavior. See 27.6.2.1/2, in particular:

"... Both groups of output functions generate (or _insert_)
output characters by actions equivalent to calling
rdbuf->sputc(int_type). They may use other public members of
basic_ostream except that they do not invoke any virtual
members of rdbuf() except overflow()."
