[Boost-users] [newbie] Boost 1.39 in Mac XCode get "error: attempt to copy-construct an iterator from a singular iterator."

Hi, I'm new to boost. It seems that the coding of boost library is not very clean as it makes the debug code aborted by generating a runtime error like this: "error: attempt to copy-construct an iterator from a singular iterator.". Here are the steps to reproduce the fault: I downloaded the source and install the things to /usr/local/include as well as /usr/local/lib. I test the code by creating a "C++ Tool" project in XCode. 1. Create a new C++ Tool project. 2. Add the header search path /usr/local/include/boost-1_39 and library search path /usr/local/lib into the project. 3. Add "Other Linker Flags" "-lboost_system-xgcc40-mt" in the project setting. 4. Edit the main.cpp as below: #include <iostream> #include int main (int argc, char * const argv[]) { boost::asio::io_service io_service; boost::asio::ip::tcp::acceptor acceptor(io_service); std::cout<<"acceptor instantiated."<
