Build fails with (signal: 11, SIGSEGV: invalid memory reference)

I had previously waited for https://github.com/rust-lang/rust-bindgen/issues/493 to be closed as I had hoped this would fix it for my case, a libfive wrapper, too.

However, it still persists:

error: failed to run custom build command for `libfive-sys v0.1.0 (/Users/moritz/code/crates/libfive-sys)`

Caused by:
  process didn't exit successfully: `/Users/moritz/code/crates/libfive-sys/target/debug/build/libfive-sys-8ef0dc6589c9b81d/build-script-build` (signal: 11, SIGSEGV: invalid memory reference)

The repository is here.
Requires --recursive cloning.
I am building on macOS. The README has instructions for dependencies.

I am only including libfive.h in my wrapper.hpp.

Libfive uses C++17 features. The previous version I tried to wrap, in January, was just using C++11 features. I.e. I doubt this is related.

Just run cargo build on latest nightly to reproduce.

Clone virtualritz/libfive-sys recursively on macOS, follow its README dependency instructions, and run cargo build on the latest nightly to reproduce the build-script-build SIGSEGV. Start with the wrapper.hpp inclusion of libfive.h and the generated build entry point. Done means the project builds without the invalid-memory-reference failure.
