Martin,

Here is an attasched example that reproduces the problem.

Regards,
Jeff Franks.

#include <sigc++/sigc++.h>
#include <iostream>

// compile with: g++ test_bind.cc -o test_bind `pkg-config sigc++-2.0 --cflags --libs`

struct Data
{
};

class Widget : public sigc::trackable
{
	Widget(const Widget&);
	Widget& operator=(const Widget&);

public:
	Widget()
	{
	}
};

class Object : public sigc::trackable
{
	Object(const Object&);
	Object& operator=(const Object&);

	typedef sigc::slot<bool, Widget&> Slot;
	Slot slot_;

public:
	Object(const Slot& slot)
	: slot_(slot)
	{
	}
};

bool foo(Widget& widget, Data *data)
{
	std::cout << "inside foo" << std::endl;
	return true;
}

int main(int argc, char *argv[])
{
	Data *data = new Data;
	Object object(sigc::bind<0>(sigc::ptr_fun(&foo), data));
	return 0;
}
