            Bug ID: 97092
           Summary: Object generation numbers aren't updated (except in
                    the xref table)
           Product: poppler
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
          Assignee: poppler-bugs at lists.freedesktop.org
          Reporter: jakubkucharski97 at gmail.com

If you update an object, its generation number will only be incremented in the
cross-reference table, but e.g. not in the object header or, if it is the
"Info" dictionary, in the "Info" entry of the trailer dictionary.

To reproduce this bug, update an object (e.g. modify a single annotation in
evince) and use "tail" unix utility with the "-n" option big enough (e.g. 100)
to see the object header of the updated object. No matter how many times you
update the object, the generation number is still the same. The generation
number in the cross-reference table will be updated though.
