Bug#975931: libllvm11: libgpuarray autopkgtest using pocl on armhf triggers segfault

[Drew Parsons]

Source: pocl
Version: 1.8-2
Followup-For: Bug #975931

pyopencl passes tests now on several arches with pocl 1.8-2 (llvm 11)
from experimental, though armhf still fails.

You reported that pocl 1.8 supports llvm 13.  Can we try that now, and
upload to unstable?  Would also fix Bug#1001317.

Hi,

I just gave it a new try and switched pocl 1.7-3 in experimental to use
llvm 11 ...
https://buildd.debian.org/status/package.php?p=pocl&suite=experimental

The segmentation fault now happens not only on armhf, but also on armel
and amd64 (buildd with amd cpu, I cannot reproduce this locally on an intel 
cpu).

The segfault also seems to happen on ppc64el and s390x, but pocl never
built on these architectures due to other failing tests.

This issue seems to persist with LLVM 12, too. (LLVM 13 is not supported
by pocl 1.7, will be in pocl 1.8)
