Hi!

I'm afraid i can't discribe the problem very well, so please see the code:

#include <boost/signal.hpp>
#include <iostream>
using namespace std;

typedef boost::signal<void ()> signal_t;
typedef boost::signals::connection connection_t;

signal_t g_signal;

void test_b()
{
cout << "b" << endl;
}

void test_a()
{
cout << "a" << endl;
g_signal.connect(test_b);
}

int _tmain(int argc, _TCHAR* argv[])
{
connection_t t = g_signal.connect(test_a);
g_signal();
t.disconnect();
g_signal();

return 0;
}

int the function test_a , I perfer call test_b next signal that mean output is "a b"

but test_b is called immediately and the output is "a b b"

how can I solve the problem?
