#65 buffer overflow detected during attempted recovery of zip

Hi! We at openSUSE also are experiencing similar errors when using FORTIFY_SOURCE=3. You can try by compiling zip using -DFORTIFY_SOURCE=3 and using the following command line:

$ touch α.txt
$ zip a.zip α.txt

Another point for you, I attempted to report this bug by the link http://www.info-zip.org/zip-bug.html but it results in an error about an empty README or some such.
