Boost signals2 automatic connection management and changing the mutex type of a signal

Question

I am trying to use automatic connection management and changing the mutex type of a signal for a template function.

The following code compiles and executes fine usi

Answer 1

I examined the code, but couldn't find the immediate cause of the error. By once assigning &Simple::proxy to equivalent variable as the following, VC compiled the code somehow:

template < typename F, typename ST, typename A1 >
boost::signals2::connection connectAutoMgmt( F f, ST st, A1 a1 ) {
    void (Simple::*p)( F, ST, int ) = &Simple::proxy;
    return sig.connect( sig_type::slot_type( p, .... ).track( st ) );
}

void init() {
    ....
    void (Simple::*p)(
      void(Simple::*)(int), boost::shared_ptr< Simple >, int ) =
      &Simple::proxy;

    boost::signals2::connection c2 = sig.connect(
        sig_type::slot_type( p, .... ).track( s2 ) );    
    ....

However, I cannot figure out why the above changes have an effect. Honestly I suspect VC's bug at the moment... Anyway, hope this helps.
