BOOST_MPL_ASSERT is broken in VC12 (VC++2013RC)

[abyx@…]

Code:

#include <boost/mpl/assert.hpp>

struct true_type {
    static const bool value = true;
};

struct pred {
    typedef true_type type;
};

static_assert(pred::type::value == true, ""); // ok
BOOST_MPL_ASSERT((pred)); // error (line #12)

Well, it seems it was already fixed in trunk.
Sorry for false alert.

It was fixed in r84443 in May, but that won't make any release compatible with VS2013. Can someone please merge that revision to the release branch?

[Daniel James]

This was eventually merged in r86514.
