--- Comment #4 from rubykuby at gmail.com ---
Nailed down the bug to commit 1f6c0b55df9f3553b18062ad2c7e2dc021d4c731:

    radeonsi: set number of userdata SGPRs of GS copy shader to 4

    It only needs the constant buffer with clip planes and read-write resources
    for the GS->VS ring and streamout. That's 2 pointers.

The commit before that commit (68d36c0bb532987db27a596408e0326f20ca0365) does
not crash and burn.

Used the following configure command for each build:

./autogen.sh --prefix=/usr/local \
               --sysconfdir=/etc \
               --with-dri-driverdir=/usr/lib/xorg/modules/dri \
               --with-gallium-drivers=r300,r600,radeonsi,nouveau,svga,swrast \
               --with-dri-drivers=i915,i965,r200,radeon,nouveau,swrast \
               --with-egl-platforms=x11,drm,wayland \
               --disable-xvmc \
               --enable-llvm-shared-libs \
               --enable-egl \
               --enable-gbm \
               --enable-gallium-llvm \
               --enable-shared-glapi \
               --enable-glx \
               --enable-glx-tls \
               --enable-dri \
               --enable-osmesa \
               --enable-gles1 \
               --enable-gles2 \
               --enable-texture-float \
               --enable-xa \
               --enable-vdpau \
               --enable-omx \
               --enable-nine \
               --enable-opencl \
               --enable-opencl-icd \
               --with-clang-libdir=/usr/lib

Followed by make and make install.

Running on Arch Linux currently, with the following package versions:

xorg-server - 1.16.4-1
xf86-video-ati - 1:7.5.0-1
linux - 3.18.6-1
