Delete 3D array causes segmentation fault

Question

So I'm having trouble deleting a 3D array. It seems to cause a segmentation fault in my code. This is what I have. The segmentation fault is caused by the deletion of the 3D array, but I don't know why.

int main( int argc, char** argv ) 
{
  //variables
  ifstream inputFileStream[ argc - 2 ];
  int ***dimensions;

  //open inputFileStream and read in values...

  //creating the dynamic 3D array and reading in grey values
  dimensions = new int**[ argc - 2 ];
  for( int i = 0; i < argc - 2; i++ )
  {
      dimensions[ i ] = new int*[ width ];
      for( int j = 0; j < width; j++ )
      {
          dimensions[ i ][ j ] = new int[ height ];
          for( int k = 0; k < height; k++ )
          {
              inputFileStream[ i ] >> dimensions[ i ][ j ][ k ];
          }
      }
  }

  //do something with array

  //delete array
  for( int i = 0; i < width; i++ )
  {
      for( int j = 0; j < height; j++ )
      {
          delete[] dimensions[ i ][ j ];
      } 
      delete[] dimensions[ i ];        
  }
  delete[] dimensions;
}

When allocating, your 'i' value goes from 0 to 'argc-2', your 'j' value goes from 0 to 'width', and your 'k' value corresponds to 'height'. When deleting, your 'i' value goes from 0 to 'width', and your 'j' value goes from 0 to 'height'. Yet you index with [i][j] in both cases. This is not consistent.
