Visual Studio debugger glitch in 64 bits?

Question

C++ / C#

void func(RECT rect)
{
  // здесь уже другие координаты
}

RECT r2;
r2.bottom = 0;
r2.right = 0;
r2.left = 0;
r2.top = 0;

func(r2);

everything is fine in 32 bits, in 64 - a glitch (?):

Update: this is a glitch of the VS2008 SP1 debugger . Maybe someone knows how to fix it?
There is information that in Visual Studio 2010 the same (!)

Answer 1

there is either a debugger or a compiler buggy. Try like this:
void func(RECT& rect) { RECT r = rect; // и дальше работаем с r a = r.right; }

Answer 2

show assembly code. It seems that this function is not called at all in the optimized code, since there is only initialization of a temporary variable in the function body.

Answer 3

in 2012 studios there is no such problem.
