Package: release.debian.org Severity: normal Please block yesterdays llvm-toolchain-9 binNMU 1:9.0.1-20+b1 (and probably any further binNMUs as well) from migrating to testing. It introduces a regression when compiling OpenCL code from pocl by segfaulting in libclang-cpp9 (#1000838). Simple reproducer: apt-get install pocl-opencl-icd clinfo clinfo So far I could observe these segmentation faults on amd64, i386, arm64.
According to Sylvestre, this will be fixed only by the removal of llvm-toolchain-9. Andreas
