Julia 1.4 uses LLVM_VER = 8.0.1, which has breaking changes relative to LLVM_VER = 6.0.1 used by Julia 1.3. I think even source build won't work until Cxx.jl is updated...

Thanks for your quick response! Now I'm getting a curl 404 error: ``` │ curl: (22) The requested URL returned error: 404 │ make: *** [BuildBootstrap.Makefile:23: llvm_tars] Error 22 ```

These are the broken urls: ``` http://releases.llvm.org/8.0.1/llvm-8.0.1.src.tar.xz http://releases.llvm.org/8.0.1/cfe-8.0.1.src.tar.xz http://releases.llvm.org/8.0.1/compiler-rt-8.0.1.src.tar.xz http://releases.llvm.org/8.0.1/libcxx-8.0.1.src.tar.xz http://releases.llvm.org/8.0.1/libcxxabi-8.0.1.src.tar.xz http://releases.llvm.org/8.0.1/polly-8.0.1.src.tar.xz http://releases.llvm.org/8.0.1/libunwind-8.0.1.src.tar.xz http://releases.llvm.org/8.0.1/lld-8.0.1.src.tar.xz ``` These urls work fine if I replace 8.0.1 with 6.0.1. Looks like [https://releases.llvm.org/6.0.1](https://releases.llvm.org/6.0.1) contains source...

This issue has nothing to do with Docker. I've been seeing the same thing with Ryzen 5900x (without Docker) and was just about to file a new issue. Cxx works...
