A core dump is a snapshot of the process memory at the time it received the signal which caused the core. Often, this occurs due to invalid memory accesses in the file. If the core contains debug info (and sometimes if it doesn't), you can use it to help track down what happened by loading the core along with the binary which produced it into a debugger like gdb.
