Comment:

 This is likely caused by the fact that _internal_accept_owner doesn't
 check whether _owned isn't already true. The following simpler test also
 crashes:

 {{{
 #include <boost/shared_ptr.hpp>
 #include <boost/enable_shared_from_this.hpp>

 struct X: public boost::enable_shared_from_this< X >
 {
 };

 struct null_deleter
 {
     void operator()( void const* ) const
     {
     }
 };

 int main()
 {
     boost::shared_ptr<X> px( new X );
     boost::shared_ptr<X> px2( px.get(), null_deleter() );
 }
 }}}
