之前运行正常的代码,因为项目需要,将原来的stl 的list改为map,编译正常,运行到此处的时候会发生异常,报告如题。怀疑自己使用map的inster或者map[i] = "";方法有问题,专门又试了下,发现都正常啊,那就从现在的代码上找问题吧。我发现了我在初始化结构体的时候,使用了memset,这个方法把map中的两个指针_left和_ri

一、map值存储的是指针 map自带的.clear()函数会清空map里存储的所有内容,但如果map值存储的是指针,则里面的值不会被清空,会造成内存泄漏,所以值为指针的map必须用迭代器清空。 1. erase迭代删除 std::map<int, HHH*> test_map; HHH* h1 = new HHH; HHH* h2 = new HHH; test_map[0] = h1; test...

报segmentation fault(core dump) gdb ./test test.core如果生成的是test.core. 当我们的程序崩溃时,内核有可能把该程序当前内存映射到core文件里,方便程序员找到程序出现问题的地方。最常出现的,几乎所有C程序员都出现过的错误就是“段错误”了。也是最难查出问题原因的一个错误。下面我们就针对“段错误”来分析cor...

If a Linux user process accesses an address to which it does not have access, a segmentation fault (segfault) occurs and the process is killed by the OS. Since the DSP has no MMU, it can not be restricted to certain memory addresses, which means that a "rogue pointer" in DSP-side ...
