Package: llvm Version: 1:21.1.6-70 Severity: normal Tags: upstream I have come across this issue when trying to use a self-built current development version of pocl on by Debian sid machine with rusticl installed, and is caused by multiple concurrent factors.
For work, I need to build the pocl CUDA backend, which refuses to build against llvm 21 because of this bug https://github.com/llvm/llvm-project/issues/154772 that has apparently been fixed in this LLVM commit: https://github.com/llvm/llvm-project/pull/170170 The issue manifests differently depending on which version of rusticl I have installed and how pocl is built. Some of the combinations I've tried are: mesa-opencl-icd 25.3.3-1, custom pocl built against llvm 18: running some OpenCL programs on the rusticl platform segfaults in the constructor for clang::DiagnosticOptions, called by clc_compile_to_llvm_module from clc. mesa-opencl-icd 25.3.3-1, custom pocl built against llvm 19, mesa-opencl-icd 26.0.0~rc3, custom pocl built against llvm 18: segfault is triggered in the rusticl platform devices enumeration during a full `clinfo` when the rusticl platform tries to build the simple kernels used to check preferred workgroup size multiples. mesa-opencl-icd 25.3.3-1, custom pocl built against llvm 18 with -DSTATIC_LLVM=ON: crashes `clinfo -l` during the pocl device numeration, with the well-known : CommandLine Error: Option 'internalize-public-api-file' registered more than once! LLVM ERROR: inconsistency in registered CommandLine options error (wow, I hadn't seen this in a LONG time). While I can probably provisionally solve my specific issue by downgrading my mesa-opencl-icd installation to the stabl version, which is built against LLVM 19, or possibly by a backport of the aforementioned 170170 PR to the LLVM 21 in Debian, the underlying issue remains that it is still impossible to have multiple OpenCL ICD versions using different LLVM / libclang versions in the same system. -- System Information: Debian Release: forky/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.18.9+deb14-amd64 (SMP w/16 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages llvm depends on: ii llvm-21 1:21.1.8-3 ii llvm-runtime 1:21.1.6-70 llvm recommends no packages. llvm suggests no packages. -- no debconf information
