Core dumps are generated when the process receives certain signals, such as SIGSEGV, which the kernels sends it when it accesses memory outside its address space. Typically that happens because of errors in how pointers are used. That means there’s a bug in the program. The core dump is useful for finding the bug.
How does core Dump work Linux?
The Linux kernel can write a file containing the state of a process when the process receives certain signals, e.g. segmentation fault or illegal instruction. Such files are called core dumps and contain a snapshot of the allocated memory and registers and can later be used with gdb to analyse the causes of the signal.
