*That's* interesting.

How did you get this image? It seems to have an incorrectly-formed 
ZLibReadStream class. Is this a virgin image or have you loaded some other 
change sets besides official updates?

There should only be the 'crc' instance variable (defined in InflateStream); 
the 'adler32' one got removed.

Neither FastInflateStream nor ZLibReadStream should define any instance 
variables.

Assuming that you loaded updates 5758 and 5810 in the right order, this should 
be the case.

At least it is in the image that I have (which I updated from an earlier 
version).

Check to make sure that you have loaded the 5758PNGReadWriterV7 update (the V7 
is important) as well as 5810ZipCrcTests.
