Upstream bug report: https://github.com/llvm/llvm-project/issues/63110 Can't reproduce anymore with LLVM 16.0.6 / 17.0.0 rc1 / 18.0.0_pre20230803 (https://github.com/llvm/llvm-project/issues/63110#issuecomment-1666653795) |
sys-devel/llvm-17.0.0_pre20230520 fails to compile with previous snapshot (llvm/clang 17.0.0_pre20230512) with -flto (lld and mold) Reproducible: Always Steps to Reproduce: 1. emerge =sys-devel/llvm-17.0.0_pre20230512 --deep --with-bdeps=y (lld and -flto=thin, clang/musl profile including llvm-libunwind / libomp / libcxx/-abi, compiler-rt/-sanitizers without binutils) 2. switch compiler to llvm-17.0.0_pre20230512 3. emerge =sys-devel/llvm-17.0.0_pre20230512 --deep --with-bdeps=y (-flto, mold or bfd or lld) Actual Results: segfault with backtrace during linking Expected Results: compilation works fine with thinlto Options that might be required for reproducing segfault libc version: musl-1.2.4 additional package from overlay: - sys-libs/libexecinfo-1.9 (linked during
