对于Linux,Mac OS X,android，如果你使用gcc或者编译器使用glibc，你能使用backtrace()函数来打印堆栈信息，backtrace在execinfo.h中申明。   
这里有一个例子，安装一个SIGSEGV处理用来打印stacktrace到stderr。baz()函数引发一个异常。

#include <stdio.h>
    #include <execinfo.h>
    #include <signal.h>
    #include <stdlib.h>
    #include <unistd.h>
    
    
    void handler(int sig) {
      void *array[10];
      size_t size;
    
      // get void*'s for all entries on the stack
      size = backtrace(array, 10);
    
      // print out all the frames to stderr
      fprintf(stderr, "Error: signal %d:\n", sig);
      backtrace_symbols_fd(array, size, STDERR_FILENO);
      exit(1);
    }
    
    void baz() {
     int *foo = (int*)-1; // make a bad pointer
      printf("%d\n", *foo);       // causes segfault
    }
    
    void bar() { baz(); }
    void foo() { bar(); }
    
    
    int main(int argc, char **argv) {
      signal(SIGSEGV, handler);   // install our handler
      foo(); // this will call foo, bar, and baz. baz segfaults.
    }

编译使用-g -rdynamic取得符合信息。

$ gcc -g -rdynamic ./test.c -o test

这里例子执行输出：

$ ./test
    Error: signal 11:
    ./test(handler+0x19)[0x400911]
    /lib64/tls/libc.so.6[0x3a9b92e380]

关于android如何实现

这里有一个android下的开源实现   
[https://github.com/SalomonBrys/\_\_deprecated\_\_Native-Crash-Handler][https_github.com_SalomonBrys_deprecated_Native-Crash-Handler]   
这个版本在native代码奔溃后，俘获并且发送一个java异常。这样ACRA可以进行统一的报告出来。
