C++ Release版本发布到客户处执行时，如果程序崩溃，有什么办法能够快速的确认程序的问题呢？
- 如果能gdb调试的话，比较简单了，可以使用gdb命令，类似如下：
gdb ##
set args ****
b main
r
#eip
x/10i 0xb7362040
- 如果开发不在现场等情况，此时可以使用记录崩溃日志的方法进行分析
此时首先要求的是项目使用类似google breakpad这个工具库，对崩溃进行记录
默认breakpad生成的是dmp文件，可以使用breakpad带的工具转换成文字进行查看，如下：
./minidump-2-core -m 7ee5c76f-afe2-f9bd-564dedb7-57d73e0c.dmp >core
./minidump_stackwalk 7ee5c76f-afe2-f9bd-564dedb7-57d73e0c.dmp > dbg.txt
此时根据如上的信息可以确定哪个模块的地址出错了
由于一般的情况，发布的库的源代码对应版本提取，编译比较麻烦，可以直接拿对应出错的库或执行文件进行分析，使用objdump生成出汇编文件，通过对应地址可以初步找到哪个函数出问题，至于猜测出来的代码，那需要根据分析情况构建单元测试或者重新上线进行检验
具体的一些过程实例如下：
objectdump -d ##.so > ##.o
vim ##.o
