     Hi Robert,
     
     This compiles fine on 586 Linux with CVS GCC.  Is this
     target specific, or is it fixed for you too?

>Description:
The following code (by N. Josuttis, p.669- of his book) does not produce the expected output (i.e. 31 HEXADECIMAL: 1F):


#include <iostream>
#include <streambuf>
#include <locale>
#include <cstdio>

class outbuf : public std::streambuf
{
  protected:
    /* central output function
     * - print characters in uppercase mode
     */
    virtual int_type overflow (int_type c) {
        if (c != EOF) {
            // convert lowercase to uppercase
            c = std::toupper(c,getloc());

            // and write the character to the standard output
            if (std::putchar(c) == EOF) {
                return EOF;
            }
        }
        return c;
    }
};

int main()
{
    outbuf ob;                // create special output buffer
    std::ostream out(&ob);    // initialize output stream with that output buffer

    out << "31 hexadecimal: " << std::hex << 31 << std::endl;
}
>How-To-Repeat:
The next example in the book too (outbuf1x.cpp & outbuf1x.hpp) does not produce the expected output

P.S.: Thanks to Benjamin Kosnik for having fixed the bug I previously reported!
