我有一个在 Solaris 中运行的 RPC 服务器。我有一个在 Solaris 中运行良好的 RPC 客户端。当我在 Linux（RHEL 5 或 6）中编译和运行相同的代码时，我在服务器中收到错误解码参数。我应该如何发现问题？
代码的某些部分是：
/* now allocate a LoopListRequestStruct and fill it with request data */
llrs = malloc(sizeof(LoopListRequestStruct));
fill_llrs(llrs);
/* Now, make the client request to the bossServer */
client_call_status = clnt_call(request_client, ModifyDhctState,
(xdrproc_t)xdr_LoopListRequestStruct,
(caddr_t)llrs,
(xdrproc_t)xdr_void,
0,
dummy_timeval
);

/* DhctState_d, and the PackageAuthorization_d */
dl = llrs->ARG_PTR->loopList.Loop_List_val;
dl->Descriptor_Loop_len = 2;
dl->Descriptor_Loop_val =
malloc((2 * sizeof(Resource_descriptor_union)));
/* now, populate each descriptor */
