If the running programs were terminated abnormal or crashed, the memory status of the program will be recorded by OS and saved in a file, this file is called “Core Dump” . We also can think of core dump as “memory snapshots”, but in fact, in addition to the memory core dump information, some crucial state of program will also be dump down, such as register information (including the program pointer, the stack pointer etc.), memory management information, other processor state.
