Limited C ++ Distribution Size

I am using Visual Studio 2008. I dynamically declared the big_massive variable:

unsigned int *big_massive = new unsigned int[1073741824]

But when I tried to debug this program, I got the following error: Invalid allocation size: 4294967295 bytes. Hope there is some way to avoid such a mistake? Thank!
