ill-formed iostream code code in section 34.2 of User Guide
-----------------------------------------------------------

                 Key: STDCXX-1024
                 URL: https://issues.apache.org/jira/browse/STDCXX-1024
             Project: C++ Standard Library
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 4.2.1
            Reporter: Martin Sebor
            Assignee: Martin Sebor
             Fix For: 4.2.2


As mentioned in this [post|http://markmail.org/message/36yuvstyykkgr3zo], the example program
in section 34.2.3 -- Using Pointers or References to Streams of the User Guide is ill-formed:

  at the very end of http://stdcxx.apache.org/doc/stdlibug/34-2.html
there is an example of using a reference to create a "copy" of cout.
However this example doesn't initialize the defined reference at once
(which is required in C++) and for this reason doesn't compile with my
gcc 4.2.1.

  For convenience here is the example:

int main(int argc, char *argv[])
{
  std::ostream& fr;
  if (argc > 1)
    fr = *(new std::ofstream(argv[1]));
  else
    fr = std::cout;

  fr << "Hello world!" << std::endl;

  if (&fr!=&std::cout)
    delete(&fr);
}
{quote}
