Bug ID: 52637
           Summary: comctl32:listbox test_LBS_NODATA() fails in the
                    Japanese and Chinese locales
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: comctl32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When running comctl32:listbox test_LBS_NODATA() fails in the Japanese and
Chinese locales:

listbox.c:2630: Test failed: Unexpected return value 5.
listbox.c:2630: Test failed: Unexpected return value 5.

https://test.winehq.org/data/patterns.html#comctl32:listbox

5 is the number of TCHARs returned by LB_GETTEXTLEN but the test expects either
4 or 8 for 32- and 64-bit processes respectively.

The failures are systematic and, as far as I can tell, happen on any machine
given the right locale (for instance LANG=ja_JP.UTF8).

Also a bisect pointed to this commit as the trigger for the failures:

user32: Introduce get_class_info.

And use it in WIN_CreateWindowEx to trigger class registration.
