ulimit -c unlimited does not generate a core file in c++ segmentation fault

Question

When I get a segmentation fault (core dump) in a c++ programm I don't get the core file after type the command: ulimit -c unlimited.

It is the first time that I see that, and I do not why.

You want to take a look at the content of:

/proc/sys/kernel/core_pattern

… which enables the system to store your core file as a given name and/or behind a given path, and even pipe it to a command if needed.
