Not sure if this is the same issue. My student found an issue with x64 bit CRC calcualations when the file length was sufficient that the value needed to roll over. I believe that the patch has been applied to trunk.

Hi, Michael. The issue was reproduced on RHEL 5 x86_64, gcc 4.1.2.
zlib version is 1.2.3. (I think it's the latest).
Should note that msvc9 + zlib1.2.3 built from sources seems to be ok.
