Windows 32-bit builds failing

These two builds on 32-bit windows failed.

Looking at where the tests fail, it seems that they were copying the 1d array into VirtualArray rather than just having the pointer to the original array.

Though, it is odd that some 1d array tests failed and some others passed.

I don't think I have access to a 32-bit windows computer so I don't think I will be able to debug this one.

Took a guess at the issue and was right, fixed in PR #5.
