Description of problem:
I have written a snippet of code to generate core dump.
File: a.c

#include <stdio.h>
char **c;

gcc a.c -o a -g

In fedora 25 after segmentation fault, core dump  file is not being created. 

I have also set the core file to unlimit with the command ulimit -c unlimited.

Please check the contents of /proc/sys/kernel/core_pattern.  As far as I know, f25 uses systemd-coredump by default.  The core dumps are then available via coredumpctl(1).

Note that you can use gdb(1) to create core dumps manually anytime anywhere.
