I can provide one:
struct A {
  char const* src;
  char* dest;
};

void f1(char const** src, char** dest) {
  A a;
  a.src= *src;
  a.dest= *dest;
  for(int i = 0; i < 10; ++i)
    *++a.dest = *++a.src;
  *src = a.src;
  *dest= a.dest;
}

void f2(char const** src1, char** dest1) {
  char const* src = *src1;
  char* dest = *dest1;
  for(int i = 0; i < 10; ++i)
    *++dest = *++src;
  *src1 = src;
  *dest1 = dest;
}
