expected calloc out put

[Sharyathi Nagesh]

Hi
	ltp test suite tests for 2 successive calloc()s like this 
=====================
#include<stdio.h>
#include<stdlib.h>
#include<errno.h>
#define MAX 8092*8092
int main()
{
        char *ptr1,*ptr2;
        ptr1=calloc(MAX,1);
        perror("calloc 1:");
        ptr2=ptr1;
        free(ptr1);
        perror("free ");
        ptr1=calloc(MAX,1);
        perror(" calloc 2");
        if(ptr1 == ptr2)
                printf("\n Success");
        else
                printf("\n Failure");
}
=====================
fails in ppc 64 specifically. The test suite fails as ptr1 is not equal
to ptr2. Is calloc() expected to return same values on successive
allocation? as man page doesn't suggest any thing on this.
 Please let us know of your opinion.
