Hello Jakob, or anyone else affected,

Accepted gcc-4.8 into trusty-proposed. The package will build now and be

few hours, and then in the -proposed repository.

Please help us by testing this new package.  See

Title:
  GCC miscompilation with boost::asio::io_service::work

Status in gcc-4.8 package in Ubuntu:
  Incomplete
Status in gcc-4.9 package in Ubuntu:
  Fix Released
Status in gcc-4.8 source package in Trusty:
  Fix Committed
Status in gcc-4.9 source package in Trusty:
  Invalid

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.
