Sorry: nice long holiday break. So calling that library a "left over from a previous build" confuses me. What's the point of the `-DLLVM_DIR=/home/freik/src/rel-llvm/lib/cmake/llvm` argument to the second cmake config if not to instruct the build where to find stuff from the full LLVM build? If I delete that library, I can, indeed, reproduce the issue [now working on it] but that also leads me to believe that my repro still isn't actually doing what your configuration is. Because of that, I have no confidence that what I do to fix the issue is going to *actually* fix it 😞
