Hi,

it looks like using boost::multi_index::member<> crashes MSVC 2015 RTM 
when a const-qualified type is passed to it as the 2nd argument, but the 
member is actually non-const.

#include <boost\multi_index_container.hpp>
#include <boost\multi_index\member.hpp>
#include <boost\multi_index\indexed_by.hpp>
#include <boost\multi_index\ordered_index.hpp>

struct X {
   int number; // non-const
};
using namespace boost::multi_index;
int main() {
   typedef multi_index_container<X, indexed_by<ordered_unique<member<X, 
const int, &X::number> > > > C;
   C c;
   c.find(1); // C1001
   return 0;
}

...\include\boost\multi_index\member.hpp(65): fatal error C1001: An 
internal error has occurred in the compiler.
   (compiler file 'f:\dd\vctools\compiler\utc\src\p2\main.c', line 246)

I found the following on a related subject, but I'm not sure whether 
this is a separate issue or not.
