Compilers are evolving: they issue more and more warnings. Do developers still need to use static code analyzers like PVS-Studio? Yes, because analyzers are evolving too. In this article you'll see how PVS-Studio can find bugs even in a compiler.
Examples of errors that PVS-Studio found in LLVM 15.0
by Andrey Karpov
From the article:
It's a cool bug, although it's not scary. There is no semicolon after the return statement. As a result, the code does not work as it looks.
void FunctionLoweringInfo::ComputePHILiveOutRegInfo(const PHINode *PN) { .... Register DestReg = It->second; if (DestReg == 0) return assert(Register::isVirtualRegister(DestReg) && "Expected a virtual reg"); LiveOutRegInfo.grow(DestReg); .... }

PVS-Studio 7.21 has been released. This short note describes the analyzer's main enhancements and lists our recent articles and quizzes.
PVS-Studio 7.21: GitLab Code Quality, Unreal Engine
by Sergey Vasiliev
From the article:
New C++ diagnostics:
- V1090. The 'std::uncaught_exception' function is deprecated since C++17 and is removed in C++20. Consider replacing this function with 'std::uncaught_exceptions'.
- V1091. The pointer is cast to an integer type of a larger size. Casting pointer to a type of a larger size is an implementation-defined behavior.
- V1092. Recursive function call during the static/thread_local variable initialization might occur. This may lead to undefined behavior.

The ACCU is now putting together its program, and they want you to speak on C++. The ACCU conference has strong C++ tracks, though it is not a C++-only conference. If you have something to share, check out their
Call for Papers
by the ACCU
About the conference:
The ACCU 2023 conference will be from 2023-04-19 to 2023-04-22, with pre-conference workshops on 2023-04-17 and 2023-04-18.
The ACCU 2023 will be a hybrit event.
Historically, ACCU has a lot of C++ and C content, and is proud of that: ACCU is the foremost annual conference for people interested in C++ and C, at least in and around the UK. But it is not just a C++ and C conference, ACCU is about programming in whatever language people are using, with whatever tools and processes people are using: D, Chapel, Java, Kotlin, C#, F#, Groovy, Rust, Go, Python, Ruby, Lisp, to name just a few programming languages about which there have been sessions at ACCU conferences. Git, Mercurial, CMake, Meson, TDD, BDD, all these tools and techniques have been the focus of sessions at ACCU. The ACCU Conference is looking for sessions that will be interesting to people who create software.
The ACCU Conference is put on by ACCU (https://accu.org), but is open to anyone who wishes to be there either as a presenter or an attender.The Call for Papers lasts for about 3 weeks and will close on Monday 7th November 2022 at 23:59:59 GMT.

New in this month's Overload magazine:
The power of ref-qualifiers
by Andreas Fertig
From the article:
... What I have illustrated is that there is an issue with range-based
for-loops. In (1), we callGetKeeper().items()in the head of the range-basedfor-loop. By doing this, we create a dangling reference.ref-qualifiers to the rescue
Now, this brings us to ref-qualifiers. They are often associated with
movesemantics, but we can use them withoutmove. However, we will soon see why ref-qualifiers make the most sense withmovesemantics.A version of
Keeperwith ref-qualifiers looks like Listing 2...
