[minicoredumper] Invalid stack when all memory regions are dumped

[Abhi Arjun]

Thanks for your reply. 
I just use a simple test program.  Stack size is 8KB
Regards,
Abhi

~/mini$ cat cd.c
#include <stdio.h>
#include <stdlib.h>
#include <assert.h>

int main()
{
    int a=10;
    printf("Test Program\n");
    assert(0);
}
~/mini$ ulimit -a
stack size              (kbytes, -s) 8192
