RuntimeError: memory access out of bounds

Som of my Rust queue consumers throw exceptions very frequently before even starting the queue event handler, see https://github.com/cloudflare/workers-rs/issues/374. Or it times out without anything happening. It somehow feels like there's an issue outside of my code. Any idea what could cause this? I've tried instrumenting for a core dump, but the recordCoredump in wasm-coredump expects a request object, see https://github.com/cloudflare/wasm-coredump/issues/3.
