I recently cleaned up and streamlined the implementation of the "dataflow
iterators" in my local copy.  I don't know if this will make the above
disappear.  I sort of doubt it.  I'm suspicious of the transition from char
to const char.  I'll look at this.

This looks like a compiler issue in getting bool/int confused. Try 
Changing 

        basic_text_oprimitive<std::ostream>(
            os, 
            0 != (flags & no_codecvt)
        )
At around line 63 in file text_oarchive.hpp to

        basic_text_oprimitive<std::ostream>(
            os, 
            static_cast<bool>(0 != (flags & no_codecvt))
        )
