Bug ID: 91520
Summary: [radeonsi, PIGLIT, regression]
spec@arb_gpu_shader_fp64@execution@fs-indirect-temp-do
uble-{dst,src} triggers SIGSEGV
Product: Mesa

Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Keywords: regression
Severity: normal
Priority: medium

GDB: backtraces and register info for crashes
For two builds now I'm seeing the two Piglit tests
spec@arb_gpu_shader_fp64@execution@fs-indirect-temp-double-{src,dst} crash in
radeonsi_dri.so.
dmesg shows:
> shader_runner[26631]: segfault at 2017f9ba1 ip 00007f16519bd800 sp 00007ffc79c82250 error 6 in radeonsi_dri.so[7f165140f000+7d3000]
Attached you'll find the GDB output (full backtrace, full register info) for
the crashes triggered by both tests with my current stack (see below for
details).
The last known good Mesa version was Git:master/bb9d59aed5 (build date
2015-07-26). The first known failing build was Git:master/fdb8487613 (build
date 2015-07-30). The LLVM revision used for the fdb8487613 build was r243627
(LLVM SVN trunk, 3.8-devel). Sadly I can't seem to find the LLVM revision used
by the bb9d59aed5 build anylonger. But it was probably a build of a revision
from that day, since I'm using the snapshot builds from <http://llvm.org/apt>,
which are done twice per day.
My current stack (Debian testing as a base):
GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1)
Mesa: Git:master/5d29eaef85
libdrm: 2.4.62-1
LLVM: SVN:trunk/r243678 (3.8 devel)
X.Org: 2:1.17.1-2
Linux: 4.1.3
Firmware: <https://secure.freedesktop.org/~agd5f/radeon_ucode/hawaii/>

I had the same problem with libelf1 0.163-4 (was fine with libelf1 0.159-4.2).
I rebuilt Mesa against libelfg0-dev instead of libelf-dev, and the problem is
gone for me.
If you can confirm this, please file a bug against libelf1.

Indeed, libelfg0 (0.8.13-5) works! Thanks for the pointer.
