[Boost-users] [Lambda, Function, etc] Is static dangerous?

Hi All Is it dangerous to write static Boost.Functions or Boost.Lamda placeholders in a multi-theaded context? I think that might be a really stoopid quesion - I'm just checking! Thx - Rob. eg, #include <boost/function.hpp> #include <boost/lambda/bind.hpp> void f( ) { namespace ll = boost::lambda; using boost::function; typedef std::pair<int, int> int_pair; static ll::placeholder1_type x; static function<int(const int_pair &)> second = ll::bind( & int_pair::second, x ); }
