===== test_void_pointers

tool: D17: Set void pointer to the address of an int: `void *p = &i`. Address: %p


tool: D44: Casting a void pointer to assumed type and dereferencing: `*(int*)p`. Returns %d


tool: D10: Set int pointer equal to void pointer: `int *int_p = p`

tool: D39: But would not stop you setting float pointer equal to void pointer that points to int: `float *float_p = p`

tool: D43: Dereferencing the float pointer doesn't blow up (since float and int both 4 bytes), but value is wrong: %f
