WinDbg
OllyDbg
SoftICE （已经停止更新）
虽说WinDbg在无源码调试方面确实比较困难，但在调试内核方面却真的有独到之处。

使用Windbg解析dump文件
1 常用的Windbg指令
①!analyze -v
②kP 可以看函数的入参
③!for_each_frame dv /t 可以看函数中的局部变量
④dc , db 产看某一内存中的值 可以直接接变量名 不过可能需要回溯栈
⑤!threads 显示所有线程 ⑥~0s ， ~1s 进入某个线程
⑦!frame ProcessA!FunctionA 查看某一变量有时需要。 回溯栈
⑧!uniqstack 扩展命令显示当前进程中所有线程的调用堆栈，除开重复的那些。
⑨!teb 扩展以的格式化后的形式显示线程环境块(TEB)的信息。
⑩s-sa 和 s-su 命令搜索未指定的 ASCII 和 Unicode 字符串。这在检查某段内存是否包含可打印字符时有用。
⑪dds、dps 和 dqs 命令显示给定范围内存的内容。 该内存被假定为符号表中的一连串地址。相应的符号也会被显示出来。命令显示给定范围内存的内容,它们是把内存区域转储出来，
并把内存中每个元素都视为一个符号对其进行解析，dds是四字节视为一个符号，dqs是每8字节视为一个符号，dps是根据当前处理器架构来选择最合适的长度
⑫.kframes 命令设置堆栈回溯显示的默认长度。默认20
⑬k, kb, kd, kp, kP, kv (Display Stack Backtrace) k*命令显示给定线程的调用堆栈，以及其他相关信息。通常要结合12)使用否则显示出来的东西很少
⑭.reload /i xxx.dll 忽略.pdb 文件版本不匹配的情况。
2 Symbol的设置方法
2.1 将远程的系统函数的PDB文件拷贝到本地「D:\mysymbol」目录下
SRV*D:\mysymbol*http://msdl.microsoft.com/download/symbols 2.2 加载设置的符号文件
.reload
可以使用菜单中的 Debug -> Modules 查看有没有加载进来

错误代码：0xc0000374
错误含义：ACTIONABLE_HEAP_CORRUPTION_heap_failure_buffer_overrun
第一步、先用「!analyze -v」分析出错误的地方以及由于什么原因导致程序Dump掉的。
无非是内存溢出，访问非法地址等几种。

第二步、使用「!heap」找出出错的堆。分析出错的原因。
0000000000c59c80
0000000000c59e50 ←出错的堆地址。
0000000000c59fd0
大家应该有这样的常识，在使用malloc()或者realloc()分配出来的空间的前面都有
相应的管理情报，用来记录这块分配的内存的大小以及返回的时候用的情报。
从这里很自然的猜想到，在写往0000000000c59c80里面写数据的时候写过了，
写到0000000000c59e50上去了，导致它的管理情报被覆盖了。从而程序dump掉了。

第三步、使用「!for_each_frame dv /t」打印出错函数的局部变量，找出元凶。
从下面的变量里面找到距离0000000000c59c80地址最近的变量，对了就是它:
char * pData_n = 0x00000000`00c59c90 "SE:Security: ???"
※注意如果变量值指针的指针需要先用dc看一下该指针指向的地址。
之后看代码知道，程序在读取pData_n的数据的时候如果遇到是0a(Windos换行符)就自动在后面加上0d变成0a0d。导致pData_n内存越界了。0a------换行符号－－－－－－"\n"
0d------回车符号－－－－－－"\r"
一般在windows系统中两个连用，"\r\n"------0d0a

这次运气很不好，从「!analyze -v」打出来的结果来看看不出啥东西来，只知道
在调用strncpy_s的时候dmp掉了，无法定位具体是哪个函数出错的原因很多，有可能
客户采集的不是全dmp文件或者dmp文件中的栈被破坏了。
这的确很伤脑筋，就针对这个我可是花了3个星期一行行的解析栈里面的内容 才解决的。
第二步、先用「!teb」看一下这个程序的栈是从哪里到哪里的。

★「ProcessB2!work」的内容本应该是像这样的数据「DNxxxxxxxx_150_109」
但是现在「ProcessB2!work」中的内容却是「VIP_rtcrx00184-004a/b-y3b-d」这个。
00000000`001247f8 00000000`005782c0 ProcessB2!trcData
▲「ProcessB2!trcData」的内容是「Function:testB call」。
函数List::testB の trace("testB", __FILE__, __LINE__, TRCLV_3);

这里终于定位到是哪个函数出问题。搞清楚这些函数的功能，然后打印出所有可能打印的内容，发现
函数传递了一个不合法的数据。在这里要说一下为啥传的数据不合法就会Dmp掉。
首先strncpy 这个函数在使用的时候只要有个宏定义(默认是有的)在编译的时候就会使用strncpy_s这个安全函数。
详情可以参考下面微软的说明文档。
http://msdn.microsoft.com/zh-cn/LIBRARY/ms175759(v=vs.80)
其次说明一下为什么会dmp掉。strncpy在使用的时候如果转化成strncpy_s的时候是这样一种形式。
char dst[5];
strncpy(dst, "a long string", 5); ----> strncpy_s(dst, 5, "a long string", 5);
而这样就会到时报STATUS_INVALID_PARAMETER这个错误这是strncpy_s的特性。具体使用方法可以参考下面的文档。
http://msdn.microsoft.com/zh-cn/library/5dae5d43(v=vs.90).aspx
节选:
char dst[5];
strncpy_s(dst, 5, "a long string", 5);
means that we are asking strncpy_s to copy five characters into a buffer five bytes long; this would leave no space for the null terminator, hence strncpy_s zeroes out the string and calls the invalid parameter handler.
If truncation behavior is needed, use _TRUNCATE or (size – 1):
strncpy_s(dst, 5, "a long string", _TRUNCATE);
strncpy_s(dst, 5, "a long string", 4);详细的ACTIONABLE_HEAP_CORRUPTION_heap_failure_buffer_overrun方法还:
