Anybody had problems with boost::signal? The following
sample code crashes on my Win2k/VC++6 system.
struct HelloWorld
{
void operator()() const
{
}
};
// Signal with no arguments and a void return value
boost::signal0<void> sig;
// Connect a HelloWorld slot
HelloWorld hello;
sig.connect(hello);
// Call all of the slots
sig();
It crashes when find_if() is calling the functor. For
some reason the functor is bad.
template<typename IteratorAdaptor>
void increment(IteratorAdaptor& x)
{
++x.base();
x.base() = std::find_if(x.base(),
x.policies().end,
std::not1(is_disconnected()));
cache.reset();
}
