Fun with -fsanitize=undefined and Picolibc Both GCC and Clang support the -fsanitize=undefined flag which instruments the generated code to detect places where the program wanders into parts of the C language specification which are either undefined or implementation defined. Many of these are also common programming errors. It would be great if there were sanitizers for other easily detected bugs, but for now, at least the undefined sanitizer does catch several useful problems. Supporting the

C and C++ Prioritize Performance over Correctness PDF Posted on Friday, August 18, 2023. The original ANSI C standard, C89, introduced the concept of “undefined behavior,” which was used both to describe the effect of outright bugs like accessing memory in a freed object and also to capture the fact that existing implementations differed about handling certain aspects of the language, including use of uninitialized values, signed integer overflow, and null pointer handling. The C89 spec define

OnlyFans fined over user age-check information failings OnlyFans' parent company has been fined £1.05m after giving inaccurate information about the measures it had in place to check the age of its users. The platform - which is known for hosting sexually explicit material - says people who visit it must be at least 18 years old. It uses facial age estimation technology - provided by a third party - where a selfie is analysed to work out how old a prospective user is. The platform's owner, F

Ofcom had pressed the platform - which is known for hosting sexually explicit material - about how it was implementing age checks. The platform's owner, Fenix, said it used so-called facial age estimation technology - provided by a third party - which was set to flag anyone who appeared to be under the

A Guide to Undefined Behavior in C and C++, Part 1 Also see Part 2 and Part 3. Programming languages typically make a distinction between normal program actions and erroneous actions. For Turing-complete languages we cannot reliably decide offline whether a program has the potential to execute an error; we have to just run it and see. In a safe programming language, errors are trapped as they happen. Java, for example, is largely safe via its exception system. In an unsafe programming languag
