Comment (by Alan Yuelkenbeck <ayuelkenbeck@…>):

 = Fixed the formatting =

 * Works fine when not compiled with -std=c++0x.
 * GCC v. 4.6.3 on ubuntu 12.04
 * Linking to static libboost_thread, libboost_system (1.50.0 release
 config)
 * Does not matter if server code is listening or not.

 Minimal reproducible code below:

 {{{
 #!c++
 int main(int argc, char *argv[])
 {
     boost::asio::io_service service;

     using namespace boost::asio::ip;

     tcp::resolver resolver(service);
     tcp::resolver::query query(tcp::v4(), "127.0.0.1", "50001");
     tcp::resolver::iterator itr = resolver.resolve(query);

     if (itr != tcp::resolver::iterator())
     {
         tcp::socket s(service);
         boost::asio::connect(s, itr); // Segmentation Fault Here
     }
 }
 }}}

 Callstack:
 {{{
 boost::asio::detail::reactive_socket_service_base::close(this=0x16,
 impl=..., ec=...) (reactive_socket_service_base.ipp:103)

 boost::asio::detail::default_connect_condition>(s=..., begin=..., end=...,
 connect_condition=..., ec=...) (connect.hpp:120)
 boost::asio::connect<boost::asio::ip::tcp,
