#11702: boost::bind universal reference handling regression
---------------------------------+------------------------
 Reporter:  maxim.yegorushkin@…  |      Owner:  pdimov
     Type:  Bugs                 |     Status:  new
Milestone:  To Be Determined     |  Component:  bind
  Version:  Boost 1.59.0         |   Severity:  Regression
 Keywords:  bind, auto_ptr       |
---------------------------------+------------------------
 The following code compiles with boost-1.57 but not with boost-1.59:

 {{{
 #include <boost/function.hpp>
 #include <boost/bind.hpp>
 #include <memory>

 void foo(std::auto_ptr<int>);

 int main() {
     boost::function<void(std::auto_ptr<int>)> f = boost::bind(foo, _1);
     std::auto_ptr<int> p;
     f(p);
 }
 }}}

 This is due to the new universal reference handling code implemented in
 boost::bind.

 The local fix we use is:

 {{{
 #if !defined( BOOST_NO_CXX11_RVALUE_REFERENCES )

 namespace boost { namespace _bi {

 template<class A> struct list_add_cref<std::auto_ptr<A> >
 {
     typedef std::auto_ptr<A>& type;
 };

 } }

 #endif
 }}}
