2248	BLL constifies return values of operator*	thomas weidner <thomas_weidner@…>	No-Maintainer	"Hi, the problem can quickly described as
{{{
( *_1 = 0 ) ( shared_ptr<int>(new int) );
// vs
( *_1 = 0) ( new int );
}}}
only the second line compiles. I tracked down the problem to boost/lambda/operator_return_type_traits.hpp:230. The BLL sets the return type of (const shared_ptr<int>)::operator*() to be const int& rather than int&. This is like turning int * const into int const *. I (and others) don't see a reason for this specialization, the code above works with the specialization removed.
