Bug Description

The following program should keep running forever until it's being killed:

#include <boost/asio.hpp>

int main()
{
    boost::asio::io_service io_service;
    boost::asio::io_service::work work(io_service);

    boost::system::error_code ec;
    io_service.run(ec);

    std::cout << ec.value() << " - " << ec.message() << std::endl;

    return 0;
}

However, on gcc 4.8.2-19ubuntu1 which ships with Ubuntu 14.04 Trusty (amd64 version), it returns right away with output "0 - Success".
Switching to clang++ makes the snippet behave as intended.
Boost.Asio is a header-only library, so compilers matter.

Hello Jakob, or anyone else affected,

Accepted gcc-4.8 into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gcc-4.8/4.8.4-2ubuntu1~14.04 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!
