title: How to verify 64 bit compatibility?
body: <p>I'd like to ensure that my 32bit ported code works correctly when the memory allocation address goes into the >4GB memory range.</p>
  
  <p>Is it a good idea to allocate 4GB in my main method at the beginning ?</p>
  
  <p>Is it better to set the base address outside the 32bit range ?
  Is it necessary to set the base address in every dynamically linked library ?</p>
  
  <p>Not necessary to mention that i already looked at static code analyzer results and reviewed my code. </p>
