About the release:

In a sense, this is a milestone for us. The thing is that we cannot add more numbers of general analysis warnings, otherwise they will concur with the numbers of micro-optimization diagnostics. It seemed to us that the list of 300 diagnostics was endless, but now it is over and we got to the point of 800, where we have micro-optimization diagnostics. In the next release we plan to resume numbering the general-analysis warnings with V1000. Download and enjoy the new version of PVS-Studio now by clicking here.

The compiler is to blame for everything—Andrey Karpov

Many programmers are very fond of blaming the compiler for different errors. Let's talk about it.

The compiler is to blame for everything

by Andrey Karpov

From the article:

When a programmer tells you that the compiler causes an error, it is a lie in 99% of cases. When you start investigating the problem, you usually find out the following reasons:

  • an array overrun;
  • an uninitialized variable;
  • a misprint;
  • a synchronization error in a parallel program;
  • a non-volatile variable used;
  • code leading to undefined behavior;
  • etc.
