#5616: No output when using a filtering_ostream pointer

     Type:  Bugs              |      Status:  new      
Milestone:  To Be Determined  |   Component:  iostreams
  Version:  Boost 1.46.1      |    Severity:  Problem  
 Keywords:                    |  
------------------------------+---------------------------------------------
 When creating a filtering_ostream on the heap, the output is empty.

 Following code works:

 {{{
         boost::regex pattern("...");
         boost::iostreams::regex_filter filter(pattern,"...");
         boost::iostreams::filtering_ostream out;
         out.push(filter);
         out.push(std::cout);
         out<<"I am written to std::cout"<<endl;
 }}}


 However, following code does not. Nothing is printed on the standard
 output:

 {{{
         boost::regex pattern("...");
         boost::iostreams::regex_filter filter(pattern,"...");
         boost::iostreams::filtering_ostream &out = *new
 boost::iostreams::filtering_ostream();
         out.push(filter);
         out.push(std::cout);
         out<<"I am not written to std::cout!"<<endl;
 }}}
