            Bug ID: 43340
           Summary: valgrind shows several possible leaks in several tests
                    (e.g., dlls/amstream/tests/amstream.c) (AMD+llvm mesa)
           Product: Wine
           Version: 2.12
          Hardware: x86
                OS: Linux
            Status: NEW
          Keywords: download, source, testcase, valgrind
          Severity: normal
          Priority: P2
         Component: advapi32
          Assignee: wine-bugs at winehq.org

      Distribution: ---

Glx info:
OpenGL renderer string: Gallium 0.4 on AMD OLAND (DRM 2.49.0 /
4.9.33-vanilla-workstation-3, LLVM 3.9.1)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.0.6
OpenGL core profile shading language version string: 4.50
OpenGL version string: 3.0 Mesa 17.0.6

Henri and I briefly discussed on IRC, not likely an issue:
<wizardedit> strfllw, looking at valgrind + mesa with debugging info fixed
(march disabled); I see a lot of possible leaks, could you take a quick look
please? e.g., d3d10core/device: https://pastebin.com/URY5kwxu
<strfllw> wizardedit: I'd have to take a much closer look to say for sure, but
purely by "gut feeling" I'd say probably not
<strfllw> my guess would be valgrind not understanding ralloc in the first one,
and not understanding Mesa's shader cache for the others

Filing a bug for reference / place holder in case someone does want to
investigate.
