reflect: call of reflect.Value.Int on ptr

服务器运行几个月了，最近突然panic在rpc的gob encode函数中，应用层逻辑很简单，所以暂时不太清楚是哪里的问题，正在学习go的rpc源码和gob编码的源码。panic信息如下： ``` panic: reflect: call of reflect.Value.Int on ptr Value [recovered] panic: reflect: call of reflect.Value.Int on ptr Value goroutine 52598456 [running]: encoding/gob.catchError(0xc4209e10d0) /root/go/src/encoding/gob/error.go:38 +0x95 panic(0xc40860, 0xc42606ad00) /root/go/src/runtime/panic.go:489 +0x2cf reflect.Value.Int(0xbcdec0, 0xc4251fe520, 0x196, 0x196) /root/go/src/reflect/value.go:902 +0xb5 encoding/gob.encInt(0xc423ab4ae0, 0xc422da1e40, 0xbcdec0, 0xc4251fe520, 0x196) /root/go/src/encoding/gob/encode.go:188 +0x43 encoding/gob.(*Encoder).encodeStruct(0xc4209e1040, 0xc4209e1078, 0xc421a28a20, 0xcc1be0, 0xc4251fe510, 0x199) /root/go/src/encoding/gob/encode.go:334 +0x256 encoding/gob.(*Encoder).encode(0xc4209e1040, 0xc4209e1078, 0xcc1be0, 0xc4251fe510, 0x199, 0xc4209c3480) /root/go/src/encoding/gob/encode.go:707 +0x1d3 encoding/gob.(*Encoder).EncodeValue(0xc4209e1040, 0xc95bc0, 0xc4251fe510, 0x16, 0x0, 0x0) /root/go/src/encoding/gob/encoder.go:250 +0x3ab encoding/gob.(*Encoder).Encode(0xc4209e1040, 0xc95bc0, 0xc4251fe510, 0x0, 0x0) /root/go/src/encoding/gob/encoder.go:175 +0x61 net/rpc.(*gobServerCodec).WriteResponse(0xc422b51ec0, 0xc422d737d0, 0xc95bc0, 0xc4251fe510, 0xc422b43a40, 0xc422b4a350) /root/go/src/net/rpc/server.go:424 +0x1dd net/rpc.(*Server).sendResponse(0xc420055680, 0xc422b45aa0, 0xc421c4ff00, 0xc95bc0, 0xc4251fe510, 0x1334ac0, 0xc422b51ec0, 0x0, 0x0) /root/go/src/net/rpc/server.go:366 +0x130 net/rpc.(*service).call(0xc422afe900, 0xc420055680, 0xc422b45aa0, 0xc422b4ec00, 0xc421c4ff00, 0xbc3800, 0xc427ab07e0, 0x16, 0xc95bc0, 0xc4251fe510, ...) /root/go/src/net/rpc/server.go:394 +0x22e created by net/rpc.(*Server).ServeCodec /root/go/src/net/rpc/server.go:481 +0x404 ``` 源码大致如下： ```go type RpcArgs struct{ A string B int32 C string D int32 E String F int32 G int32 H int32 I bool J string K int32 L String M int32 N int32 O int32 P bool } func RPC1(args *RpcArgs, reply *int){ //some simple logic .... //do another async rpc call,and then painc in gob encode rpc.Client.Go(serviceMethod, args, reply, make(chan *rpc.Call, 1)) } ``` 在encodeStruct里，紧接着调用的是encInt函数，但是最终panic时发现要解析的数据类型是Ptr.不知道有人遇到过这样的问题没，谢谢！
