Improve memory leak detection for multidimensional array

[lefreut]

Hello,

cppcheck does not find the memory leak in this code:

int main()
{
  int ** foo = new int*[2];
  foo[0] = new int;
  delete [] foo;
  return 0;
}

Looks like a duplicate/variation of #114.

No meleak warning with malloc either:

int main() {
  int** foo = (int**)malloc(2 * sizeof(int*));
  foo[0] = (int*)malloc(sizeof(int));
  free(foo);
}

[chrchr]
