Bug ID: 56568
           Summary: There is a memory leak vulnerability in line 909 of
                    the /wine/tools/winegcc/winegcc.c file
           Product: Wine
           Version: 9.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

In the file winegcc.c located at /wine/tools/winegcc/, a pointer variable named
libgcc is defined at line 881. On line 907, this variable allocates a block of
dynamic memory using the function xmalloc. When the if statement on line 909
evaluates to true, the program returns. During this process, the dynamically
allocated memory pointed to by the variable libgcc is neither returned as on
line 914 nor freed, thus causing a memory leak defect, as shown in the diagram
below:
