Bug ID: 51456
           Summary: oleaut32:typelib: test_CreateTypeLib(SYS_WIN32) fails
                    in 64-bit Wine
           Product: Wine
           Version: 6.10
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: oleaut32
          Assignee: wine-bugs@winehq.org
          Reporter: fgouget@codeweavers.com
      Distribution: ---
oleaut32:typelib has many failures in 64-bit Wine, the first one of which is
because Wine returns the wrong size for a structure:
https://test.winehq.org/data/patterns.html#oleaut32:typelib
typelib.c:2169: Test failed: retrieved IUnknown gave wrong cbSizeVft: 24
In the SYS_WIN32 case cbSizeVft should be 3 * 4 = 12 but it is still set to 24
by MSFT_DoTypeInfo():
ptiRet->typeattr.cbSizeVft = tiBase.cbSizeVft;
It makes sense for cbSizeVft to be 24 on the 64-bit side, but somewhere there
should be code to adjust it to account for the SYS_WIN32 on 64-bit case. But I
don't know where that should happen.
