我将使用在Visual Leak Detector中为泄漏内存生成堆栈跟踪的代码。不过，这只适用于Win32。

如果你仍然想像我一样独自去做，你可以链接到bfd，避免使用addr2line，就像我在这里所做的:

https://github.com/gnif/LookingGlass/blob/master/common/src/platform/linux/crash.c

这将产生输出:

[E]        crash.linux.c:170  | crit_err_hdlr                  | ==== FATAL CRASH (a12-151-g28b12c85f4+1) ====

它看起来就像在最后一个c++增强版本中出现的库提供了你想要的东西，可能代码会是多平台的。 它是boost::stacktrace，你可以像在boost sample中那样使用:

#include <filesystem>
#include <sstream>
#include <fstream>
#include <signal.h>     // ::signal, ::raise
#include <boost/stacktrace.hpp>

const char* backtraceFileName = "./backtraceFile.dump";

void signalHandler(int)
{
    ::signal(SIGSEGV, SIG_DFL);
    ::signal(SIGABRT, SIG_DFL);
    boost::stacktrace::safe_dump_to(backtraceFileName);
    ::raise(SIGABRT);
}

void sendReport()
{
    if (std::filesystem::exists(backtraceFileName))
    {
        std::ifstream file(backtraceFileName);

        auto st = boost::stacktrace::stacktrace::from_dump(file);
        std::ostringstream backtraceStream;
        backtraceStream << st << std::endl;

        // sending the code from st

        file.close();
        std::filesystem::remove(backtraceFileName);
    }
}

int main()
{
    ::signal(SIGSEGV, signalHandler);
    ::signal(SIGABRT, signalHandler);

    sendReport();
    // ... rest of code
}

在Linux中编译上面的代码:

g++ --std=c++17 file.cpp -lstdc++fs -lboost_stacktrace_backtrace -ldl -lbacktrace

从boost文档复制的反向跟踪示例:

0# bar(int) at /path/to/source/file.cpp:70
1# bar(int) at /path/to/source/file.cpp:70
2# bar(int) at /path/to/source/file.cpp:70
3# bar(int) at /path/to/source/file.cpp:70
4# main at /path/to/main.cpp:93
5# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
6# _start

看:

男人3回溯

And:

#include <exeinfo.h>
int backtrace(void **buffer, int size);

这些是GNU扩展。

可能值得一看谷歌Breakpad，这是一个跨平台崩溃转储生成器和处理转储的工具。

除了上面的答案，这里还介绍了如何让Debian Linux操作系统生成核心转储

Create a “coredumps” folder in the user's home folder Go to /etc/security/limits.conf. Below the ' ' line, type “ soft core unlimited”, and “root soft core unlimited” if enabling core dumps for root, to allow unlimited space for core dumps. NOTE: “* soft core unlimited” does not cover root, which is why root has to be specified in its own line. To check these values, log out, log back in, and type “ulimit -a”. “Core file size” should be set to unlimited. Check the .bashrc files (user, and root if applicable) to make sure that ulimit is not set there. Otherwise, the value above will be overwritten on startup. Open /etc/sysctl.conf. Enter the following at the bottom: “kernel.core_pattern = /home//coredumps/%e_%t.dump”. (%e will be the process name, and %t will be the system time) Exit and type “sysctl -p” to load the new configuration Check /proc/sys/kernel/core_pattern and verify that this matches what you just typed in. Core dumping can be tested by running a process on the command line (“ &”), and then killing it with “kill -11 ”. If core dumping is successful, you will see “(core dumped)” after the segmentation fault indication.
