Package: libboost-dev Version: 1.33.1-4 Severity: normal Tags: patch this simple source:
#include <boost/bind.hpp>
#include <boost/signal.hpp>
struct connection
{
boost::signal<void()> disc_sig;
};
struct statement
{
statement(connection & c);
void disconnect() {}
};
statement::statement(connection & c)
{
c.disc_sig.connect(boost::bind(&statement::disconnect, this));
}
compile with no problem on g++-4.0, but with g++-4.1 this is the
output:

The attached simple patch seem to be a solution.
This bug make me unable to package wengophone-ng for sid with gcc-4.1.
