Example Code
When running clang-tidy on the attached file, I get a
clang-analyzer-core.NullDereference warning for lines 42 and 50. The route it
takes to get this issue does not appear to be valid.
On line 59, it calls `outObj.getType()` (a const function) and assumes it is
`OutsideObject::type16`. However, on line 69 it makes the same call and
assumes that it is `OutsideObject::type32`, which is not possible in the flow
of the code.</pre>
