Bug ID: 56563
           Summary: There is a memory leak defect at line 1106 in the file
                    /wine/libs/vkd3d/libs/vkd3d-shader/dxil.c.
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs@winehq.org
          Reporter: lumingying@bupt.edu.cn
      Distribution: ---
In the file /wine/libs/vkd3d/libs/vkd3d-shader/dxil.c, a pointer variable named
global_abbrev is defined at line 1085. This variable allocates a dynamic memory
area through the function vkd3d_malloc at line 1091. When the if statement at
line 1103 returns true, the function will return at line 1106. During this
process, the dynamic memory area pointed to by global_abbrev is neither
assigned to the function parameter sm6 as shown in line 1115, nor released,
thus resulting in a memory leak defect, as illustrated in the diagram below:
