"new" behavior by MSVC but is perfectly fine behavior per the C++ standard, this 0-init's
the values in the array (as if memset were called). This is the behavior we want and since
we are targetting C++03 and above, this is a non-issue. Additionally, testing this behavior
against MSVC 2008 and above (and inspecting the asm) shows we get the results we want. */
