Bug ID: 46104
Summary: Incorrect assumption results in NullDereference
warning
Product: clang
Version: 10.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Static Analyzer
Assignee: dcough...@apple.com
Reporter: jeremy.overe...@millerwelds.com
CC: dcough...@apple.com, llvm-bugs@lists.llvm.org
Created attachment 23544

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.
