           Summary: advapi32:registry - test_RegNotifyChangeKeyValue() has
                    an intermittent failure on all Windows versions
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2

Loop on test_RegNotifyChangeKeyValue() to reproduce the event failures

advapi32:registry's test_RegNotifyChangeKeyValue() has an intermittent failure
on all Windows versions:

registry.c:3471: Test failed: expected ERROR_SUCCESS, got 6
registry.c:3599: Test failed: expected WAIT_OBJECT_0, got 258

https://test.winehq.org/data/patterns.html#advapi32:registry

The failure is pretty rare so it is likely to cause false positives. The
attached patch makes it possible to systematically reproduce the issue, at
least on my test VM. With the 10000 loops I get 4 to 5 cases with the failure
(so a rate of 0.05%) and a test run still takes under 8 seconds.
