Bug with unique_ptr and /clr code in Visual Studio 2015

[John Schroedl]

FYI - I have found and reported a bug with std::unique_ptr when used in code built with /clr in VS 2015. Consider this code:

void accept_ownership( std::unique_ptr ptr ) { ... }

void test() {
std::unique_ptr mc = std::make_unique( args );

accept_ownership( std::move(mc) );
}

When accept_ownership is called in C++/CLI code, mc will be destructed and accept_ownership receives a unique_ptr pointing to freed memory. There will be a double-free at exit as well. I've reported the bug with send-a-frown and it is NOT fixed in the Update 1 RC. Let's hope it's fixed in Update 1 RTM. The code works as expected when not built with /clr. John
