请教一个关于golang debug的问题。 我在使用Shopify/sarama这个库去连接kafka时，运行程序报错，一般这种报错如何查看？ 可以看到，我这个报错堆栈信息只能回溯10层，到sarama的Open.func1这里。 `created by github.com/Shopify/sarama.(*Broker).Open.func1` ` /paic/dev/oracle/11g/odsz11g/mygo/src/github.com/Shopify/sarama/broker.go:148` 但是我没办法找到我的代码中哪个部分触发了这个函数，请问有方法再增加报错堆栈的层数吗？ ``` unexpected fault address 0xa31800 fatal error: fault [signal SIGSEGV: segmentation violation code=0x2 addr=0xa31800 pc=0xa31800] goroutine 34 [running]: runtime.throw(0x6ea68e, 0x5) /paic/dev/oracle/11g/odsz11g/go/src/runtime/panic.go:566 +0x95 fp=0xc4200a2cd8 sp=0xc4200a2cb8 runtime.sigpanic() /paic/dev/oracle/11g/odsz11g/go/src/runtime/sigpanic_unix.go:27 +0x288 fp=0xc4200a2d30 sp=0xc4200a2cd8 github.com/rcrowley/go-metrics.(*StandardHistogram).Update(0xc4201d6060, 0x1) /paic/dev/oracle/11g/odsz11g/mygo/src/github.com/rcrowley/go-metrics/histogram.go:199 +0x3d fp=0xc4200a2d50 sp=0xc4200a2d30 github.com/Shopify/sarama.(*Broker).updateRequestLatencyMetrics(0xc4201582c0, 0x166b87) /paic/dev/oracle/11g/odsz11g/mygo/src/github.com/Shopify/sarama/broker.go:656 +0x9b fp=0xc4200a2d78 sp=0xc4200a2d50 github.com/Shopify/sarama.(*Broker).updateIncomingCommunicationMetrics(0xc4201582c0, 0x24, 0x166b87) /paic/dev/oracle/11g/odsz11g/mygo/src/github.com/Shopify/sarama/broker.go:636 +0x39 fp=0xc4200a2d98 sp=0xc4200a2d78 github.com/Shopify/sarama.(*Broker).responseReceiver(0xc4201582c0) /paic/dev/oracle/11g/odsz11g/mygo/src/github.com/Shopify/sarama/broker.go:514 +0x77a fp=0xc4200a2f70 sp=0xc4200a2d98 github.com/Shopify/sarama.(*Broker).(github.com/Shopify/sarama.responseReceiver)-fm() /paic/dev/oracle/11g/odsz11g/mygo/src/github.com/Shopify/sarama/broker.go:148 +0x2a fp=0xc4200a2f88 sp=0xc4200a2f70 github.com/Shopify/sarama.withRecover(0xc4201d60d0) /paic/dev/oracle/11g/odsz11g/mygo/src/github.com/Shopify/sarama/utils.go:46 +0x43 fp=0xc4200a2fa8 sp=0xc4200a2f88 runtime.goexit() /paic/dev/oracle/11g/odsz11g/go/src/runtime/asm_amd64.s:2086 +0x1 fp=0xc4200a2fb0 sp=0xc4200a2fa8 created by github.com/Shopify/sarama.(*Broker).Open.func1 /paic/dev/oracle/11g/odsz11g/mygo/src/github.com/Shopify/sarama/broker.go:148 +0x8ae ```
