很多朋友都抱怨说STL出问题的时候debug很难，编译期错误算是轻的，大不了一串串令人头晕的出错信息，至少还能双击定位到错误行。而神秘的运行期崩溃才是真正令人头大的问题。-Many of my friends have complained that STL difficult to debug when problems, compile-time error light is the worst case scenario is dizziness a string of error messages, at least to the wrong location can also double-click the line. And the mysterious collapse of the operation period is the first real big problem.
