BOOST_CHECK triggers debug assertion on VS C++ 2015 RC when called from within lambda

[xxn-boost-bugs@…]

I have been trying to use boost tests on with VS C++ 2015 in conjunction with boost asio and a few lambdas. It seems like there is a problem with calling BOOST_CHECK from within a lambda that has previously been dispatched via boost::asio. The calls always look like this:

BOOST_CHECK(foo([] {BOOST_CHECK(false);});

where foo dispatches the lambda some time (depending on network transfers) after the call to foo.

This is an example stack trace for such an assertion:
