            Bug ID: 128244
           Summary: OD* files can't be opened if Zip64 was used in their
                    creation
           Product: LibreOffice
           Version: 6.2.5.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: jhudson at cedaron.com

Description:
OD* files can't be opened if Zip64 was used in their creation, despite Zip64
being part of Zip Version 6.2.0. This impacts streaming generation.

Discovered in Calc since it's the only one we mess with as of yet, but probably
all formats affected.

Note the attached export32.ods is broken for other reasons but can be
recovered; while the export64.ods is unrecoverable.

Steps to Reproduce:
Try opening export64.ods

Actual Results:
Error involving content length 0 and no content can be recovered.

Expected Results:
Like export32.ods


Reproducible: Always


User Profile Reset: No



Additional Info:
As I said, we have other generation problems because we used Excel as a
baseline and Excel just doesn't even read META-INF.

Known to be broken in latest release; even online validator doesn't recognize
Zip64 yet.
