Test header_objc_template_h failing on HEAD on macOS 10.15 #2061
Description
I cloned bindgen yesterday on my Mac, and cargo test is producing a test failure in header_objc_template_h where it's using id instead of u64, e.g.:
pub trait IFoo<ObjectType>: Sized + std::ops::Deref {
- unsafe fn get(&self) -> u64
+ unsafe fn get(&self) -> idThis looks similar to #1619 but the other way around?
I'm running on macOS 10.15.7 (not terribly up to date) with Rust/Cargo nightly (rustc 1.54.0-nightly (625d5a693 2021-06-01)) from rustup. I believe I have no libclang from anywhere other than Xcode. RUST_LOG=bindgen produces the following log info about clang versions:
[2021-06-03T15:12:09Z DEBUG bindgen] Generating bindings, libclang at /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/libclang.dylib
