Unable to create a core file for my crashed program

Question

I am using Ubuntu 12.04 LTS. I wrote a simple program as follows to create crash

// null.c
#include

int main()
{
   int *p = NULL;
   int k=*p;
          


        

Answer 1

you do not need to use core pattern. its just dumps in that format %e.%p

what you need to do is #ulimit -c unlimited

and check #ulimit -a

and confirm if core file size is set properly. You will get the core as core.pid after that.
