Enable generating core dumps

The configuration file /proc/sys/kernel/core_pattern defines the default behaviour when a crash occurs. If it contains a single word such as core, a core dump will be generated on the current directory with that name. If the first character of its content is |, then the core file will be piped to a process, such as Apport (|/usr/share/apport/apport %p %s %c).

To enable core dumps for your current terminal session ignoring the default action:

ulimit -c unlimited
