Turn up compiler warnings to level 4. I suspect you will get a warning, since this is a Microsoft extension (accepting a non-const reference to a temporary).

Is now my default!
Warning 1 warning C4239: nonstandard extension used : 'argument' : conversion from 'X' to 'X &'
This is what you should see with the highest warning level.
If you select to disable language extensions, it will yield a compile error.
