PVS-Studio Learns What strlen is All About
Somehow, it so happens that we write about our diagnostics, but barely touch upon the subject of how we enhance the analyzer's internal mechanics. So, for a change, today we'll talk about a new useful upgrade for our data flow analysis.
PVS-Studio Learns What strlen is All About
by Andrey Karpov
From the article:
Can you see it? To be honest, we did not notice it immediately and our first thought was, "Oh no, we broke something!" Then we saw what was up and took a minute to appreciate the advantages of static analysis. PVS-Studio warned: V512 A call of the 'strcpy' function will lead to overflow of the buffer 'astr'. asm.cpp 21 Still don't see the error? Let's go through the code step by step.

Finding Bugs with AddressSanitizer: MSVC Compiler--Augustin Popa
A very useful tool.
Finding Bugs with AddressSanitizer: MSVC Compiler
by Augustin Popa
From the article:
The AddressSanitizer (ASan) is generally available for MSVC since the recently-released Visual Studio 2019 version 16.9. We’ve already shown how easy it can be to find bugs in even production-ready code like EASTL. Here I’ll share an example of how it found a real bug in the MSVC compiler itself.
The idea was straightforward: ASan finds bugs, and we’re always interested in finding bugs in the compiler. Just like you can turn ASan on in your projects and run your tests, we’ve been turning on ASan on our project (the compiler) and running it on our tests. Sure enough, this found bugs...
ReSharper C++ 2021.1: Syntax Style, New C++ Features, and Improved Unreal Engine Support
ReSharper C++ 2021.1 is released!
ReSharper C++ 2021.1: Syntax Style, New C++ Features, and Improved Unreal Engine Support
by Elvira Mustafina
About the release
ReSharper C++ 2021.1 brings support for several new C++20 and C++17 language features, adds new inspections, and improves Unreal Engine support. You can now configure ReSharper C++ to match your code style even more closely with a new set of syntax style settings. The accompanying quick-fixes and context actions help you keep your code style consistent and update your code with ease.
- C++ support: class types in non-type template parameters, C++20 class template argument deduction rules, noexcept as a part of the function type, and code completion for coroutines.
- Unreal Engine: initial support for Unreal Engine 5, a postfix template for Cast, and support for the RIGVM_METHOD reflection macro.
- Syntax style: a new set of code style settings for various aspects of the C++ syntax with accompanying inspections, quick-fixes, and context actions.
- Code cleanup: new code cleanup tasks, the Cleanup selection context action, and performance improvements.
- Code analysis: inspections with quick-fixes for redundant casts, template arguments that can be deduced, and variables that can be moved to the inner scope.
