<pre>
    Until a few hours ago (July 30, 2024 15:54  UTC) the following invocation installed the `llvm-18-dev` package:

```
wget https://apt.llvm.org/llvm.sh
chmod +x llvm.sh
sudo ./llvm.sh 18
```

The missing package means that `llvm-symbolizer` is missing, which can lead to breakages when using sanitizers. For example, [CPython](https://github.com/python/cpython) has a thread sanitizer CI that suddenly broke because the suppressions file (and stack traces) no longer work.

For context, the same problem (missing `llvm-symbolizer`) happened around July 17 and seemed to be resolved around July 22. See also:

* https://github.com/llvm/llvm-project/issues/99502
* https://github.com/python/cpython/issues/121946

Note that `./llvm.sh 17` seems to continue to install `llvm-symbolizer`.
