Bug report
I'm getting several compiler warnings when compiling on Linux X86_64, wasm32-emscripten, and wasm32-wasi.
Your environment
- x86_64-pc-linux-gnu with gcc
- wasm32-emscripten with clang
- wasm32-wasi with clang

The warnings are coming from clang from WASI-SDK. These look like issues in upstream expat code.
