c++ - 使用 google breakpad 注册异常处理程序时出现总线错误

Question

我正尝试在我的应用程序中使用 google breakpad。但是我在这样做时遇到了总线错误。

示例应用程序:

#include<iostream>
using namespace std;

#include "client/linux/handler/exception_handler.h"
static bool breakpadDumpCallback(const google_breakpad::MinidumpDescriptor& descriptor, void* context, bool succeeded)
{
    return succeeded;
}


int main()
{
    cout << "Hello World! \n";

    //Adding changes for google breakpad
    static google_breakpad::ExceptionHandler* excHandler = NULL;
    cout << "Here-----------! \n";

    // delete excHandler;

    excHandler = new google_breakpad::ExceptionHandler(google_breakpad::MinidumpDescriptor("/opt/minidumps/"), NULL, breakpadDumpCallback, NULL, true, -1);

    cout << "Registered Google Breakpad exceptionHandler\n";

    int *x = NULL;
    *x = 10;

    return 0;
}

我从以下行收到错误:

excHandler = new google_breakpad::ExceptionHandler(google_breakpad::MinidumpDescriptor("/opt/minidumps/"), NULL, breakpadDumpCallback, NULL, true, -1);

输出:

Hello World!
Here-----------!
Bus error (core dumped)

我做错了什么吗？

Answer 1

请试试这个

google_breakpad::MinidumpDescriptor(std::string("/opt/minidumps/"))

如果仍然不起作用，请尝试使您的代码(完全)尽可能匹配现有的工作示例: http://fossies.org/linux/seafile-client/src/crash-handler.cpp
