I am getting following error while compiling my test with gcc 3.4.2 on
Linux:

An error occured in line performing comparison:
26: ifstream_line_iterator it( "abc" );
27:
28: BOOST_CHECK( it != ifstream_line_iterator() );
Looks like compiler end up generating copy constructor. Why did this
happend? Is there workaround?
