Bug #: 33970
           Summary: GetSecurityInfo success, but DACL pointer is NULL
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

GetSecurityInfo(GetCurrentProcess(), SE_KERNEL_OBJECT,
DACL_SECURITY_INFORMATION, 0, 0, &ppDacl, 0, &ppSecurityDescriptor) returns
ERROR_SUCCESS, but ppDacl is NULL, causing ppDacl->AclSize after that to crash.

Real world example is in closed beta, but I can provide a test case if needed.
