SIGSEGV in boost::asio::connect when compiled with g++ -std=c++0x

[Alan Yuelkenbeck <ayuelkenbeck@…>]

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:

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:

Fixed the formatting

• Works fine when not compiled with -std=c++0x.
