            Bug ID: 45590
           Summary: Possible access to unintended variable in
                    "wine/dlls/wined3d/texture.c" line 2819
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs(a)winehq.org
          Reporter: petrum(a)gmail.com

While experimenting with a CodeSonar plugin we develop, we noticed a potential
bug in file "wine/dlls/wined3d/texture.c" line 2819 function
wined3d_texture_update_overlay.
The version of the file is the one in the "stable" branch from github.

dst_surface = dst_sub_resource->u.surface;
if (dst_rect)
    surface->overlay_destrect = *dst_rect; //HERE
else
    SetRect(&surface->overlay_destrect, 0, 0,
            wined3d_texture_get_level_width(dst_texture,
dst_surface->texture_level),
            wined3d_texture_get_level_height(dst_texture,
dst_surface->texture_level));

Shouldn't dst_surface be accessed in that line instead of surface? 

Thanks,
Petru Florin Mihancea
