Segmentation fault (core dumped)
Bus error (core dumped)
The program you're running has a bug. A copy of the program's memory
has been placed in the file 'core' in your current directory (unless
something else went wrong also). If it's your own program, you're
probably using a null pointer or referencing past one end of an array
or string. Be sure to delete the 'core' file.
If it's a system program, please report it to a consultant, being sure
to specify how the problem occurred, including the commands you typed
and the files you were using. Also tell the consultant the location of
the 'core' file; don't delete it.
