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...

C++ coroutines: Accepting types via return_void and return_value
by Raymond Chen
From the article:
Last time, we built the result holder for our simple_task coroutine and showed how to move values into the holder and move them back out.
So now we’re actually going to move them in...

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.

C++ Lambda Story in Print
by Bartlomiej Filipek
About the book
I packed my knowledge about lambdas into a beautiful ebook, with lots of examples and additional descriptions. And just as with my book about C++17, I made it available at Leanpub. The platform makes it easy for me to publish new updates, and everyone who has the book can immediately access the latest changes (at no charge). Also, the platform allows you to read it as PDF and Epub, Mobi or Online.

Hightlighting a less known C++20 feature:
Mathematical constants in C++20
by Jens Weller
From the article:
When I researched the library and language features of C++20 for the Meeting C++ Community survey, this feature catched my eye.
And I thought its such a nice small feature, I should mention it on the blog. As all other C++20 blog posts right now seem to be about coroutines. It also is a nice follow up on an old blog of mine: C++ & π, where I showed the various ways of obtaining pi for C++ in 2013...
