>Description:
After compressing a 2GB file on a amd64 system, decompressing it throws up an error:

gunzip: test1.gz: invalid compressed data--format violated

This also may be a issue on other 64-bit platforms in general, but I don't have FreeBSD on any of that hardware to test this on.

>How-To-Repeat:
Compress a 4GB+ file on a amd64 system and then gunzip it.      
>Fix:
Apply patch from the GZip developers:
http://www.gzip.org/4g-patch.tar

or this patch from the amd64 list:

(Thanks to Tim Robbins)
