Description Jakub Jelinek 2009-02-05 08:36:07 EST
zdiff both in Fedora 7, 10 and rawhide is buggy, when both files are gzipped, it has correct exit status, but prints no output.
See http://bugs.debian.org/cgi-bin/pkgreport.cgi?package=434275
and zdiff.in.diff patch in recent debian packages.

Haven't checked RHEL whether the same bug exists there or not.
