Hey guys,

Would you please have it fully compatible for Windows x64?

So far when I get it to compile in 64-bit, it shows as 64-bit in phpinfo(), but when I change memory_limit in pnp.ini to something that 32-bit won't support (Eg: 4096MB) it goes blank.

Thanks

Test script:
---------------
<?php
    phpinfo();
?>

Expected result:
----------------
To show phpinfo, instead of a blank screen when memory_limit has been changed to something 32-bit won't support

Actual result:
--------------
Blank Screen.
