<pre>The Zip64 document in <span class=""><a href="http://bugs.documentfoundation.org/attachment.cgi?id=155237" name="attach_155237" title="Another pair of test files">attachment 155237</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=155237&action=edit" title="Another pair of test files">[details]</a></span> differs from that in <span class=""><a href="http://bugs.documentfoundation.org/attachment.cgi?id=155152" name="attach_155152" title="Zip64 test kit">attachment 155152</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=155152&action=edit" title="Zip64 test kit">[details]</a></span>
by including something that Info-Zip's zipinfo (i.e., `unzip -Z
path/to/file.ods`) explains as "extended local header". Both include "extra
fields" (that's natural, since [1] defines "ZIP64 extended information extra
field"), but what is in the "extended local header" in the <span class=""><a href="http://bugs.documentfoundation.org/attachment.cgi?id=155237" name="attach_155237" title="Another pair of test files">attachment 155237</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=155237&action=edit" title="Another pair of test files">[details]</a></span>
(both ODS there have it) is unclear.
In general, let's not throw in here more and more random files, and just focus
this issue on supporting of Zip64 spec (i.e., not giving a warning mentioned in
<a href="show_bug.cgi?id=128244#c5">comment 5</a>). The problem of possibly incorrect handling of "extended local
header" looks independent, and likely needs a different issue.
