           Summary: EnumCalendarInfo hangs indefinitely when iterating
                    over optional calendars
           Product: Wine
           Version: 6.22
          Hardware: x86-64

   Regression SHA1: 42ed9797b1929fc5917bd967f7062cab953fab55
      Distribution: ---

Internal_EnumCalendarInfo fails to exit enumeration loop if all of the
following conditions are met:

- ENUM_ALL_CALENDARS is specified for calendar ID.

- An optional calendar exists for the current locale, which is one of:
  Arabic, Chinese, Divehi, Persian, Hebrew, Japanese, Korean, Thai, Urdu.

- The enumerator callback function never returns FALSE.

This results in some .NET Framework 4.8 apps to hang when using certain locale
functions.
