It should only free the memory pointed by the data field, not the wasm_byte_vec_t struct itself right? Usually when the C API wants to pass a bytestring as a result, it expects the caller to provide space for the wasm_byte_vec_t, but there are cases where the C API directly return a pointer to wasm_byte_vec_t (e.g. wasmtime_frame_func_name). In that case, how do I free the struct's memory? Sounds like a minor source of leak to me, but I hope I'm wrong :)
