by Gabriel Dos Reis
Excerpt:
As approved between meetings as a current working draft base for further proposal discussion in Jacksonville.
By Andrey Karpov | Feb 1, 2018 11:55 AM | Tags: undefined behavior null malloc
Unfortunately, many programmers are careless about checking of pointers, and sometimes they deliberately do not check whether to memory was allocated or not.
Why it is important to check what the malloc function returned
by Andrey Karpov
From the article:
There are 4 reasons at once, each of them is enough to prove that it is so necessary to write a check after you call the malloc function. If someone from your team doesn't write the checks, make him read this article.
- Null pointer dereference is undefined behavior
- Null pointer dereference is a vulnerability
- Where are guarantees that dereferencing of exactly a null pointer will occur?
- Where are the guarantees that memset fills the memory in a direct order?

The Most Vexing Parse: How to Spot It and Fix It Quickly
by Jonathan Boccara
From the article:
Everyone has their little defaults. You know, that little something that they do from time to time and that gets on your nerves, even though they’re otherwise nice people?
For C++, one of these little annoyances is the most vexing parse, well, as its name suggests...

Help the compiler warn you
by Andrzej Krzemieński
From the article:
Compiler warnings are a very useful tool for detecting bugs in your program. Because you can enable them selectively, and because you can choose to turn them into hard errors on your compiler, you can in fact build a dialect, which is a safer subset of C++...

A classic error:
break and fallthrough
by Andrey Karpov
From the article:
We would like to suggest reading the series of articles dedicated to the recommendations on writing code of high quality using the examples of errors found in the Chromium project. This is the second part, which will be devoted to the switch operator and, more precisely, to the problem of a forgotten break operator...
