Thread: calloc/malloc problem

this is a unit module of a bigger program , which does permutations, the idea is to return a multidimensional array of the permutation results..but I'm getting a segmentation fault when allocation space to store the results..
can someone please tell me what I'm doing wrong?

Code:

int** permConstP(int *a, int  arrStInd, int  arrEndInd)
{
    static int ** baseColours;
   static int bcInd= 0;
  
    //internal swap function
    void swap(int *x, int *y)
    {
        int temp;
        temp = *x;
        *x = *y;
        *y = temp;
    }
    
   if (arrStInd == arrEndInd)
     {
         baseColours[bcInd]=(int*)calloc(5, sizeof(int)); // getting a segmentation fault here in debugger
        for(int i = 0; i <= arrEndInd ; i++)
        {
            //printf("%d ",a[i]);
            baseColours[bcInd][i]=a[i];
        }
        bcInd++;
     }
   else
   {
       for (int i = arrStInd; i <= arrEndInd; i++)
       {
          swap((a+arrStInd), (a+i));
          permConstP(a, arrStInd+1, arrEndInd,&baseColours, &bcInd); //backtrack
          swap((a+arrStInd), (a+i));
       }
   }
   return baseColours;
}

3. Having <= suggests off by 1 counting.
4. Why the constant 5 in your calloc.

int ** baseColours is static because the function does backtracking...I need baseColours to be the same no matter how many times the function is called..
2.well I'm not using standard c, I'm using c99 or higher...
3.that was done on purpose, there is no problem there...
4.constant five in my calloc because I know I need 5 *(sizeof(int)) to store 5 int values..
still I have no answer to the problem...
