--- Comment #3 from Lars Gullik Bjønnes <larsbj at gullik dot net> ---
This is a different code snippet to get what seems to be the same error:

---------------
#include <ostream>

int f(unsigned int datalen);

class Streambuf : public std::basic_streambuf<char> {
private:
    virtual int sync()
    {
        f(this->pptr() - this->pbase());
        return 0;
    }
};


class Stream : public std::basic_ostream<char> {
public:
    ~Stream()
    {
        buf_.pubsync();
    }
private:
    Streambuf buf_;
};

void test()
{
    Stream cs;
}
---------------

I'll add preprocessed source for that as well.
