  "message": "Set up llvm-symbolizer for some of our CI pipelines. (#9029)\n\nPrior to this, we\u0027ve been seeing unsymbolized crashes when building test files with this message: ``Stack dump without symbol names (ensure you have llvm-symbolizer in your PATH or set the environment var `LLVM_SYMBOLIZER_PATH` to point to it):``\r\n\r\n---\r\n\r\nTo get `llvm-symbolizer`, we can either install an LLVM binary distribution (https://apt.llvm.org/) into our Docker images _or_ build it from source.\r\n* Building from source ensures we have the latest code, but adds build time and test script complexity (that is spread across multiple files)\r\n* Installing also puts other LLVM binaries (like `llvm-tblgen`) on the PATH, which could be unexpected when we typically build the binaries that we need from source\r\n\r\nI tried both approaches and settled on installing into our Docker images.\r\n\r\n---\r\n\r\nProgress on https://github.com/google/iree/issues/8996",
