rust-lang/libz-sys

AI Summary: The task is to debug a compilation issue with the `libz-sys` Rust crate on macOS. The compilation hangs indefinitely when using Clang, but succeeds with GCC. The solution involves identifying and resolving the incompatibility between the crate's build process and the specific Clang version (17.0.0) or Xcode version (16.4) used on macOS Sequoia 15.5. This might involve investigating compiler flags, build scripts, or potential bugs in the crate itself.
