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/blocking_udp_echo_client.cpp

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:

This is the gdb output:

Does someone has any idea why this example does not work on mac osx? Thank you.
