In TransformAttributedType(...) when checking if _Nullable can be applied to a type it dereferences TL.getAttr() unconditionally which we can see from the code earlier in the function is not correct since it is expected to be nullptr in some cases. It looks like the correct course of action is to use TL.getModifiedLoc() over TL.getAttr()->getLocation() in the case that TL.getAttr() returns a nullptr.

Introduction
|
|
============
|
|
|
|
This document contains the release notes for the Clang C/C++/Objective-C
|
|
frontend, part of the LLVM Compiler Infrastructure, release |release|. Here we
|
|
describe the status of Clang in some detail, including major
|
|
improvements from the previous release and new feature work. For the
|
|
general LLVM release notes, see `the LLVM
|
|
documentation <https://llvm.org/docs/ReleaseNotes.html>`_. All LLVM
|
|
releases may be downloaded from the `LLVM releases web
|
|
site <https://llvm.org/releases/>`_.
|
|
|
|
For more information about Clang or LLVM, including information about the
|
|
latest release, please see the `Clang Web Site <https://clang.llvm.org>`_ or the
|
|
`LLVM Web Site <https://llvm.org>`_.
|
|
|
|
Note that if you are reading this file from a Git checkout or the
|
|
main Clang web page, this document applies to the *next* release, not
|
|
the current one. To see the release notes for a specific release, please
|
|

|
|
Potentially Breaking Changes
|
|
============================
|
|
These changes are ones which we think may surprise users when upgrading to
|
|
Clang |release| because of the opportunity they pose for disruption to existing
|
|
code bases.
|
|
|
|
What's New in Clang |release|?
|
|
==============================
|
|
Some of the major new features and improvements to Clang are listed
|
|
here. Generic improvements to Clang as a whole or to its underlying
|
|
infrastructure are described first, followed by language-specific
|
|
sections with improvements to Clang's support for those languages.

Major New Features
|
|
------------------
|
|
|
|
Bug Fixes
|
|
---------
|
|
- Fix crash on invalid code when looking up a destructor in a templated class
|
|
inside a namespace. This fixes
|
|
`Issue 59446 <https://github.com/llvm/llvm-project/issues/59446>`_.
|
|
- Fix crash when diagnosing incorrect usage of ``_Nullable`` involving alias
|
|
templates. This fixes
|
|
`Issue 60344 <https://github.com/llvm/llvm-project/issues/60344>`_.

directly rather than instantiating the definition from the standard library.
