--- Comment #10 from Mike Kaganski <mikekaganski at hotmail.com> ---
The Zip64 document in attachment 155237 differs from that in attachment 155152
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 attachment 155237
(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
comment 5). The problem of possibly incorrect handling of "extended local
header" looks independent, and likely needs a different issue.
