Please provide more information about the crash; at least the stderr output
from gimp, preferably with R600_DEBUG=cs.

Created attachment 94348
  --> https://bugs.freedesktop.org/attachment.cgi?id=94348&action=edit
dump

I noticed it suddently started working flawlessly so I asked myself what fixed
it: patches from https://bugs.freedesktop.org/show_bug.cgi?id=72785 did fix it.

I currently apply:
0001-SelectionDAG-Factor-ISD-MUL-lowering-code-out-of-DAG.patch
0002-SelectionDAG-Use-helper-function-to-improve-legaliza.patch
0001-R600-SI-Custom-select-64-bit-ADD.patch

Beware that I modified "UP.Threshold = 500" to "UP.Threshold = 100" because
"bfgminer --scrypt" didn't work otherwise.

I attached dump from R600_DEBUG=cs GEGL_USE_OPENCL=yes gimp without the
patches.

Sorry I forgot one patch:
https://bugs.freedesktop.org/attachment.cgi?id=94078

This is the one with "UP.Threshold = 100" instead of "UP.Threshold = 500"

does GIMP use OpenGL other than GEGL library?

Not sure, but I don't think so. AFAIK it' only GEGL-related stuff.

a lot of gegl tests pass OK for me on Turks.
notably clone test that includes box-blur and gaussian-blur operations passes
OK.

Can you retest with the latest llvm/mesa?

I will be able to test within a couple of months, at the moment I don't have
access to a pc with such hardware.

Is this still an issue?
gegl testsuite mostly passes with only 3 remaining tests:
contrast-curve -- 7 wrong pixels
clones -- 1 wrong pixel
noise-cell -- fail (many wrong pixels, I think their algorithm is wrong)

comment #2 also mentions that this works OK
