[Boost-users] Problem in running blocking_udp_echo_client on MacOSX

I am trying to run blocking_udp_echo_client on MacOS X http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/example/echo/blocki... I run it with argument 'localhost 9000' But the program crashes and this is the line in the source which crashes: udp::socket s(io_service, udp::endpoint(udp::v4(), 0)); this is the stack trace: #0 0x918c3e42 in __kill #1 0x918c3e34 in kill$UNIX2003 #2 0x9193623a in raise #3 0x91942679 in abort #4 0x940d96f9 in __gnu_debug::_Error_formatter::_M_error #5 0x0000e76e in __gnu_debug::_Safe_iterator<__gnu_norm::_List_iterator >, __gnu_debug_def::list, std::allocator > >
