Bug ID: 55728
           Summary: regedit.exe:regedit - test_export() sometimes gets an
                    unexpected size on Windows
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

regedit.exe:regedit - test_export() sometimes gets an unexpected size on
Windows:

regedit.c:3722: Test failed: got wrong size 4, expected 5

See https://test.winehq.org/data/patterns.html#regedit.exe:regedit

This is quite rare as it has only happened 3 times in the past 7 months:

* 2023-03-23 win21H1_newtb-w10pro64-32
* 2023-06-06 win21H2_gitlab-win10-21h2-32
* 2023-10-04 win21H1_newtb-w10pro64-en-AE-u8-32

It looks like the failing test is trying to interpret an hexadecimal registry
value as a string and sometimes gets a truncated string. I would not be
surprised if this caused Windows to use some uninitialized memory thus causing
the occasional failure.
So maybe this test should be removed.
