The problem seems to be somewhere in the constructor of 
boost::signals2::slot.

The code which led to compile errors was:

boost::signals2::signal<void (const std::wstring &, int)> mySignal;

mySignal.connect(boost::bind(&SomeMemberFunction, this, _1, _2));

Changing it to the following code compiles:

boost::signals2::signal<void (const std::wstring &, int)> mySignal;

boost::signals2::slot<void (const std::wstring&, int), boost::function<void 
(const std::wstring&, int)>> mySlot(&SomeMemberfunction, this, _1, _2);
