[Bug 55778] New: user32:win - CreateWindowEx() sometimes unexpectedly succeeds on on Windows 7
https://bugs.winehq.org/show_bug.cgi?id=55778 Bug ID: 55778 Summary: user32:win - CreateWindowEx() sometimes unexpectedly succeeds on on Windows 7 Product: Wine Version: unspecified Hardware: x86-64 OS: Windows Status: NEW Severity: normal Priority: P2 Component: user32 Assignee: wine-bugs(a)winehq.org Reporter: fgouget(a)codeweavers.com user32:win - CreateWindowEx() sometimes unexpectedly succeeds on on Windows 7: win.c:6748: Test failed: CreateWindowEx should fail win.c:6749: Test failed: IsMenu set error 0 [...] win.c:11799: Test failed: 001B01FA: expected prev 00000000, got 00A500A2 [...and always 20 more 'expected prev' failures...] See https://test.winehq.org/data/patterns.html#user32:win The first known instance happened on 2023-06-15 (none in the previous 4 months) and there have been a bit over 1 instance per month since. This test has been there for years so something else must have changed to cause these failures. * 2023-06-15 win7_newtb-w7u-2qxl * 2023-07-19 win7_newtb-w7u-2qxl * 2023-08-30 win7_newtb-w7u-2qxl * 2023-08-31 win7_newtb-w7u-2qxl * 2023-09-20 win7_newtb-w7u-2qxl * 2023-10-09 win7_newtb-w7u-2qxl test_topmost()'s "expected prev" failures always follow the initial the initial CreateWindowEx failure and never happen without it. So they can be considered to be collateral damage. Then the question is: why does CreateWindowEx() unexpectedly succeeds? The documentation says hMenu can be a 'child-window identifier, an integer value'. Could it be that sometimes the desktop window has a child window with identifier 1? (HMENU)1 is used two more times. Why don't we get failures there too? Should the test use a more unlikely value like 0xdeadbeef? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
