This will be best done within zlib, and although the patch will be
easier it will affect more software which depends on zlib. Since it is
rare and is probably due to sum buggy compression library I would
rather not.

I agree with Daniel Stenberg that this is not a curl or zlib problem,
I was just looking for a way around it until someone fixes it on the
server side.
