  1. media-libs/alsa-lib-1.0.27.2
    1. Issue: Pulseaudio-4.0 trigger in alsa-lib function snd_pcm_area_silence which fails when is alsa-lib compiled with CFLAGS="-ftree-vectorize" (equals to -O3)}}
      Freedesktop.org bug #51060
      Solution: Fixed gcc or/and alsa-lib.
      Workaround: CFLAGS="-fno-tree-vectorize" emerge -v1 alsa-lib

  1. media-libs/mesa-9999
    1. Issue: Weston render incorrectly. When is gallium-egl disabled, DRI2 take care of it. Without gallium-egl can't be used openvg.
      Workaround: --disable-gallium-egl
      Solution: Fixed gallium-egl backend.
      broken since "e64633e8c3a5498998a45ab721bf80edca101cf5 r600g,radeonsi: share r600_texture.c"
    2. Issue: Fail compile with llvm > 3.3
      Workaround: "--disable-terminfo --disable-ncurses" or/and "--with-llvm-shared-libs"
      Solution: Unknown.
    3. Issue: gallium-nine d3d state tracker not initialize correctly with CFLAGS="-ftree-vectorize" (equals to -O3)
      Workaround: CFLAGS="-fno-tree-vectorize" emerge -v1 mesa
      TODO: Check if is this caused by -ftree-vectorize
    4. Issue: gallium-nine branch in my git repo has some code different from upstream
      Workaround: use upstream for OpenCL work correctly
      TODO: Make diff, check code, gallium nine as patch.
  2. >=dev-libs/weston-1.3.0
    Issue: buildsystem fails on tests with undefined reference on lot places
    Workaround: it works when it's compiled outside portage
    Solution: fix autotools?
  3. MultiPath TCP
    Issue: Maintain patchset a top of 3.12.
  4. Qt5
    Issue: GLES2 support (only in qtgui), but opengl detect gles and qtwebkit fails compile with that setting (for now completly ignoring missing #define OPENGLES2)
    Workaround: disable gles2
    Issue: Get qt5 support into official portage.
    1. wireshark-1.11.0
      Workaround: iXit overlay.
