Display of 2D dinamic arrays

[Leonardo Giordani]

I have the following code:

#include "stdio.h"
#include "stdlib.h"
       
int main()
{
  int **p;
  int i;
    
  p = (int **)malloc(2*sizeof(int *));
    
  p[0] = (int *)malloc(10*sizeof(int));
  p[1] = (int *)malloc(10*sizeof(int));
    
  for(i = 0; i < 10; i++){
    p[0][i] = i;
    p[1][i] = i+20;
  }
    
  return 0;
}

And I was trying to display it in DDD. Through the following commands

p[0][0] @ 10
p[1][0] @ 10

I can show the right values

0|1|2|3|4|5|6|7|8|9
20|21|22|23|24|25|26|27|28|29

but if I try to show the whole 2D array through the command

p[0][0] @ 10 @ 2

I obtain something strange

0|1|2|3|4|5|6|7|8|9
0|49|20|21|22|23|24|25|26|27

The (0|49) are uninitialized values at the end of p[0][0].

Is this a bug?

Thank you
