<pre>
    I got a segfault when attempting to build llvm. I don't believe it is relevant, but it was a submodule of http://github.com/ponylang/ponyc. The crash happened at around 95% built.

[AArch64ISelLowering-018f96.zip](https://github.com/llvm/llvm-project/files/8732226/AArch64ISelLowering-018f96.zip)

This was built with the llvm version of commit hash 1f9140064dfbfb0bbda8e51306ea51080b2f7aac (last release), I am working to see if this reproduces with the most recent code on main.
