Conversely, if your program has a fault (for example, using a bad pointer) at some location in memory, you can look for the source line that is closest to the memory address.
相反,如果您的程序在内存中某个位置存在错误(例如,使用了一个错误指针),那么可以查找最接近该内存地址的源代码行。
A DSI occurs whenever a reference is made to a virtual address that is not currently loaded in physical memory (this is a page fault).
如果对当前不在物理内存中加载的虚拟地址进行引用(这是一个页面错误),则会出现DSI错误。
