[Boost-users] boost::exception - leaking error_info

This program seems to be leaking boost::exception::error_info objects. Is there something missing here? - Bruce typedef boost::error_info< struct tag_my_error, std::string > some_error_info; struct an_exception : public boost::exception, public std::exception {}; void throw_func() { BOOST_THROW_EXCEPTION ( an_exception() // no leak if next line is commented out. << some_error_info( std::string( "error message" ) ) ); } . . . BOOST_AUTO_TEST_CASE( test_exceptions ) { try { throw_func() } catch( an_exception& ) { } }
