Comment(by chsalvia_at_[hidden]):

 Actually, the best way to fix this is probably to update the high water
 mark when a call to seekoff() is made.  That way, overloading xsputn is
 unnecessary, and sputc will work properly as well.

 In basic_vectorbuf<CharVector, Traits>::seekoff(), the following line
 could be added to fix the problem:

 {{{
 if (mp_high_water < base_type::pptr()) mp_high_water = base_type::pptr();
 }}}
