Bug#456930: g++-4.3: Integer variable value lost due to optimizations?
Package: g++-4.3
Version: 4.3-20071130-1
Severity: normal
Hi,
I've got the following code to constructor an acceptor:
server::server(asio::io_service& io_service, request_handler& req_handler, int fcgi_port):
acceptor_(io_service, asio::ip::tcp::endpoint(asio::ip::tcp::v4(), fcgi_port)),
io_service_(io_service),
new_connection_(new connection(io_service, *this)),
request_handler_(req_handler)
{
#ifdef TCP_DEFER_ACCEPT
int v = true;
setsockopt(acceptor_.native(), IPPROTO_TCP, TCP_DEFER_ACCEPT, &v, sizeof(v));
#endif
acceptor_.async_accept(new_connection_->socket(), boost::bind(&server::handle_accept, this, asio::placeholders::error));
}
With CMAKE_BUILD_TYPE release, bind is called with port = 0
bind(8, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("0.0.0.0")}, 16) = 0
although I'm quite sure it should be 2711.
Without CMAKE_BUILD_TYPE release, the code works fine.
I can't guarantee this is a bug in g++ though.
I'll try to reproduce this with less code.
