core dump

A file holding a crashed program's memory and registers at the moment it died, which a debugger can open afterwards.

A core dump is a snapshot of a process written when it terminates abnormally: per-thread register state, the contents of its mapped memory (or a selected subset) and the list of loaded modules, stored as an ELF core file on Linux or a Mach-O core file on macOS, and opened post-mortem in GDB or LLDB.
