我的Go应用程序连接到IBM MQ

当我的应用程序抛出分段冲突错误（signal SIGSEGV）时，IBM MQ注册的信号处理程序使我的应用程序抛出“不带SAU ONSTACK标志的非Go代码设置信号处理程序”

那我怎么设置那个标志呢

我的代码裁判

完全错误

接收到信号11，但处理程序不在信号堆栈上
致命错误：不带SA_ONSTACK标志的非Go代码设置信号处理程序

您可以尝试设置环境变量“MQS\u NO\u SYNC\u SIGNAL\u HANDLING=true”禁用MQ的一些信号设置。这至少可以更好地了解SEGV来自何处。

您可以提供您的代码以更好地理解您的问题吗？嗨@creyD，我的代码很简单：我从IBM MQ中添加了一个参考，假设所讨论的cgo代码是您正在使用的任何客户端库的一部分或者IBM MQ，这就是问题所在，也是必须解决的问题。您实际上没有在链接中显示任何MQ代码，这很可能是您出现编码错误的地方。您可以使用MQ的go示例：和

package main

import (
    "fmt"
    "github.com/ibm-messaging/mq-golang/ibmmq"
)

type A struct {
    Str string
}

type B struct {
    Apointer *A
}

func main() {
    connectIBMMQ()

    b := B{}
    fmt.Println(b.Apointer.Str)
}

const (
    QMgrName       = `QMgrName`
    ChannelName    = `ChannelName`
    ConnectionName = `0.0.0.0(1416)`
    Username       = `username`
    Password       = `password`
)

func connectIBMMQ() {
    mqcd := ibmmq.NewMQCD()
    mqcd.ChannelName = ChannelName
    mqcd.ConnectionName = ConnectionName

    csp := ibmmq.NewMQCSP()
    csp.AuthenticationType = ibmmq.MQCSP_AUTH_USER_ID_AND_PWD
    csp.UserId = Username
    csp.Password = Password

    cno := ibmmq.NewMQCNO()
    cno.ClientConn = mqcd
    cno.Options = ibmmq.MQCNO_CLIENT_BINDING + ibmmq.MQCNO_RECONNECT + ibmmq.MQCNO_HANDLE_SHARE_BLOCK
    cno.SecurityParms = csp

    ibmmq.Connx(QMgrName, cno)
}
