[fireball] 34180: - Revert 22081 by Magnus Olsen: "fixing two hiden bug in reactos, null termante the string right at end, code tested in vs, but it seam no affact on wine test mscvrt printf test. What hell is the snprintf function call to ??". Instead of fixing "hidden bugs", it introduced a real very well hidden bug, which was overwriting the target buffer and thus corrupting everything starting from the heap, and ending with pools. It's possible to install and run OO2 Writer now. See issue #3

"fixing two hiden bug in reactos, null termante the string right at end, code tested in vs, but it seam no affact on wine test mscvrt printf test. What hell is the snprintf  function call to ??".
Instead of fixing "hidden bugs", it introduced a real very well hidden bug, which was overwriting the target buffer and thus corrupting everything starting from the heap, and ending with pools. It's possible to install and run OO2 Writer now.
See issue #3311 for more details.
