[Bug 39885] Cannot allocate more than 32gb of memory

https://bugs.winehq.org/show_bug.cgi?id=39885

--- Comment #1 from rynzar(a)gmail.com ---
The code I used was: 

#include <stdlib.h>
#include <iostream>

int main()
{
   size_t gb_in_bytes = size_t(1)<<size_t(30); // 1 GB in bytes (2^30).
   // try to allocate 1 block of 'i' GB.
   for (size_t i = 25; i < 35; ++ i) {
      size_t n = i * gb_in_bytes;
      void *p = ::malloc(n);
      std::cout << "allocation of 1 x " << (n/double(gb_in_bytes)) << " GB of
data. Ok? " << ((p==0)? "nope" : "yes") << std::endl;
      ::free(p);
   }
}
