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.
