Bug ID: 53206
           Summary: user32:win - test_topmost() has some rare failures in
                    Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

user32:win - test_topmost() has some rare failures in Wine:

win.c:11770: Test succeeded inside todo block: child should be topmost
win.c:11772: Test marked todo: child2 should be topmost
win.c:11773: Test failed: grandchild should be topmost
win.c:11781: Test failed: child should NOT be topmost
win.c:11784: Test succeeded inside todo block: grandchild should NOT be topmost
win.c:11787: Test failed: 008E0096: expected NOT topmost
win.c:11606: Test succeeded inside todo block: 5: hwnd 01AA006E is still
topmost

These failure don't seem to depend on the locale and happen on the TestBot VMs
which run fvwm. They did not happen on my box under KDE but they are pretty
rare (~1% failure rate) so there may not be enough data to draw conclusions.

They also happen outside of WineTest and have caused false positives.

--- Comment #1 from François Gouget  ---
This can also take the form of a set of 4 failures:

win.c:11636: Test failed: 00000000015A00D6: expected prev 000000000033008C, got
0000000000000000
win.c:11650: Test failed: hwnd should NOT be topmost
win.c:11652: Test failed: 00000000015A00D6: expected NOT topmost
win.c:11596: Test failed: 1: hwnd 00000000015A00D6 is still topmost

With only 2 instances in 6 months this form is pretty rare too:
