Followup-For: Bug #975931 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) Andreas
