On some of my machines (1 ubuntu 22.04, 1 Fedora 39 machine) mozangle fails to build, due to bindgen failing to generate bindings.
The binding issue, seems to be because libclang-sys includes some avx512 intrinsics headers, which use some builtin functions which libclang-sys apparently doesn't recognize.

Stdout 

The following warnings were emitted during compilation:

warning: clang: warning: argument unused during compilation: '-arch:SSE2' [-Wunused-command-line-argument]
[..redacted...]

error: failed to run custom build command for `mozangle v0.5.1 (/data/servo_dependencies/mozangle)`

Caused by:
  process didn't exit successfully: `/data/servo_dependencies/mozangle/target/debug/build/mozangle-d42dc1f97a69a009/build-script-build` (exit status: 101)

On the ubuntu machine I have clang-14 and clang-15 installed. clang maps to clang-14.
If I export CLANG_PATH=/usr/bin/clang-15 the build succeeds. libclang-sys is documented to always use the newest version of libclang that it finds, so the question is how do the clang-14 headers end up being included.

Enabling the logging feature for bindgen gave me the following output:

So this does seem to be more a bindgen issue

Maybe try different clang version (I use clang 16).

I'll close this issue, since it is a bindgen issue (rust-lang/rust-bindgen#2682).
We probably should still keep this in mind, since people will run into this occasionally.

A workaround is running

export CLANG_PATH=/path/to/newest/clang-version
