Bug ID: 56561
           Summary: There is a memory leak defect at line 494 in the file
                    /wine/dlls/dmloader/container.c.
           Product: Wine
           Version: 9.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs@winehq.org
          Reporter: lumingying@bupt.edu.cn
      Distribution: ---
Trigger Path for the Defect:
1.A variable named "pNewEntry" is defined at line 389 in the file
/wine/dlls/dmloader/container.c. This variable allocates a dynamic memory area
using the calloc function at line 391. When the switch-case block at line 492
is satisfied, the program returns at line 494. In this process, the dynamic
memory area pointed to by the "pNewEntry" pointer is neither used nor freed
like at line 547, resulting in a memory leak defect, as illustrated in the
diagram below:
