            Bug ID: 56562
           Summary: There is a memory leak defect at line 733 in the file
                    /wine/dlls/user32/dde_client.c.
           Product: Wine
           Version: 9.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs(a)winehq.org
          Reporter: lumingying(a)bupt.edu.cn
      Distribution: ---

In the file /wine/dlls/user32/dde_client.c, a pointer variable named pXAct is
defined at line 702. This variable allocates a dynamic memory area through the
function WDML_AllocTransaction at line 712. When the if statement at line 713
returns false, it means that the dynamic memory area pointed to by pXAct has
been successfully allocated. When the if statement at line 730 returns true,
the program will return at line 733. During this process, the dynamic memory
area pointed to by pXAct is not used, resulting in a memory leak, as shown in
the following diagram:
