Tests fail with `misaligned pointer dereference: address must be a multiple of 0x8`

I found out about your library this morning while I was facing a bunch of problems trying to use reqwest in a WIT-component-based environment.

This library fixes the issues I had like a charm and correctly works when I invoke the WIT exports in JavaScript.

However, I later tried to write down some tests in Rust to verify some simple HTTP requests, but they panic with the error misaligned pointer dereference: address must be a multiple of 0x8.

So I'm wondering whether this is a subtle bug or simply this library is not supposed to work in standard Rust.

I've also tried running my tests with --target wasm32-wasi but they don't even start.

What are your tests like, and how are they run? Theoretically, it can be tested because waki itself has integrated tests. However, unlike ordinary tests, it requires a special way to run:

1. Write separate test programs.
   • https://github.com/wacker-dev/waki/blob/main/test-programs/src/bin/client_get_with_query.rs
   • https://github.com/wacker-dev/waki/blob/main/test-programs/src/bin/server_hello.rs
2. Compile the above programs into WASM files.
   • https://github.com/wacker-dev/waki/blob/main/test-programs/artifacts/build.rs
3. Use wasmtime (or another runtime that supports WASI preview 2 API) to run these test programs.
   • https://github.com/wacker-dev/waki/blob/main/waki/tests/all/main.rs

Thank you so much for the directions. I was running them with cargo test just like ordinary tests. I'll take inspiration from your workflow 👍
