#1 Asio? exception on 64-Plattform

[Anonymous]

I have tried Memcache++ Client on Linux 8.04 Ubuntu, 64-Bit Version with Boost v.1.37;

Just tried Hello World Example from Quick-start (source for a month): http://pastebin.com/m3d43a386

Output then:
Hello, World!
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error> >'
what(): mutex: Invalid argument
Aborted

Do You have any Idea?
