OK seems I found the error myself. I was using

bp::nary_expr< bp::_, bp::vararg<my_grammar> >

as a rule in my_grammar, which obviously caught tag::address_of.

Is it correct for matching any nary_expr *except* address_of :
bp::nary_expr< bp::not_<pt::address_of>, bp::vararg<my_grammar> >

or is there a better way if I want to prevent a subset of tag to be used ?
