7681,Bug in indirect_streambuf::seek_impl,lodos@…,Jonathan Turkanis,"Currently indirect_streambuf::seek_impl always modifies input and output pointers with code:

setg(0, 0, 0);
setp(0, 0);

See detail/indirect_streambuf.hpp. However, this is incorrect for dual seekable streams buffers which only modifies one set of pointers on each seek (in or out). As a consequence, dual seekable devices cannot be correctly seek.
Those 2 lines should be replaced by:

if (is_convertible<category, dual_seekable>::value) {
    if (which == BOOST_IOS::in) {
        setg(0, 0, 0);
    }
    if (which == BOOST_IOS::out) {
        setp(0, 0);
    }
}
else {
    setg(0, 0, 0);
    setp(0, 0);
}
