--- Comment #7 from org.freedesktop at io7m.com ---
I'm now on:

Extended renderer info (GLX_MESA_query_renderer):
    Vendor: Intel Open Source Technology Center (0x8086)
    Device: Mesa DRI Intel(R) Sandybridge Mobile  (0x116)
    Version: 12.0.3
    Accelerated: yes

OpenGL core profile version string: 3.3 (Core Profile) Mesa 12.0.3

Linux copperhead 4.8.4-1-ARCH #1 SMP PREEMPT Sat Oct 22 18:26:57 CEST 2016
x86_64 GNU/Linux

... and I can still reproduce this problem:

$ ./bug 
GL_VERSION: 3.3 (Core Profile) Mesa 12.0.3
ASSERT: Scalar FS validation failed!
load_payload(8) vgrf3:UD, (null):UD(null):UD(null):UD, vgrf0+3.0:F 
brw_fs_validate.cpp:53: inst->src[i].reg_offset + inst->regs_read(i) <=
(int)alloc.sizes[inst->src[i].nr]
Aborted (core dumped)

Has that commit actually made it into a release yet?
