You're copying into the wrong address.

pMyStringAdresspMyStringAdress is a pointer that holds the heap address returned by VirtualAllocVirtualAlloc.

But you used &pMyStringAdress&pMyStringAdress (the address of the pointer variable on the stack) both when printing and in memcpy. That writes past the pointer variable itself and trashes the stack -> "Run-Time Check Failure #2 … stack … was corrupted."

- Fixes

Use pMyStringAdress, hence the message (no &) when printing and copying."Run-Time Check Failure #2 … stack … was corrupted."

Free with VirtualFree when done.Fixes

Minor: use the right printf specifiers.
