rubyzip fails to open a Zip64 file with a maximum length comment #509
Description
Similarly to #508, if a Zip64 archive has a maximum length comment, rubyzip cannot read it.
This is a slightly more difficult fix than for non-Zip64 files as the End of Zip64 Directory records are more complex. Fixing this properly means stepping through the archive in a more logical manner which will end up being more robust.
