Reported by John Schmidt: zlibc.crc32 doesn't appear to properly parse its seed argument. For example: ###### >>> zlib.crc32('foobar',0xFFFFFFFF)) OverflowError: long int too large to convert to int ###### This appears to be fixed if we make the included patch to zlibmodule. I haven't tested this on a 64-bit platform, though; can someone look into this? Hope this helps!
