No output when using a filtering_ostream pointer

[anonymous]

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;
