            Bug ID: 56153
           Summary: Possible nullpointer dereference in
                    wow64_NtUserUnpackDDEMessage (Coverity)
           Product: Wine
           Version: 9.0-rc3
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs(a)winehq.org
          Reporter: dark.shadow4(a)web.de
      Distribution: ---

In wow64_NtUserUnpackDDEMessage we have the following code:
> if (!params->result) NtCallbackReturn( &result, sizeof(result), TRUE );
> *params->result = result;

Not 100% sure what is intended here, but it doesn't look right.

The code is correct, NtCallbackReturn doesn't return.
