A CORE dump is the recorded state of the working memory of a computer program at a specific time, generally when the program has terminated abnormally includes the program COUNTER and stack pointer, memory management information, and other processor and operating system flags and information a fatal error usually triggers the core dump, often buffer overflows, where a programmer allocates too LITTLE memory for incoming or computed DATA, or access to null pointers, a common coding error when an unassigned memory reference variable is accessed.
