Since the goal here is to explicitly check handling pointer arithmetic, you may
want to add additional checks for the values you get this way.
`expect_var_path` returns the SBValue it has located, so you could do something
like:
```
pp_void0_2_got = self.expect_var_path("&pp_void0[2]", type="void **")
pp_void0_2_exp = self.expect_var_path("pp_void0_2", type="void **") #
Initialized in C++ code to point to the same value
self.assertEqual(pp_void0_2_got.GetValueAsAddress(),
pp_void0_2_exp.GetValueAsAddress())
```
