The Long and Winding Road to a Segmentation Fault
Description
A multi-panel comic strip, using the 'passing notes in class' meme format, illustrating the journey of a piece of code. The characters are simple stick figures, and the labels are in Russian. The sequence begins with a character labeled 'Чей-то код' (Someone's code) passing a note to 'stackoverflow'. Stack Overflow then passes the note to 'я' (I/me), who relabels it 'Мой код' (My code). This 'My code' is then passed through a long chain of characters representing a software toolchain: 'IDE', 'Статический анализатор' (Static analyzer), 'Токенизатор' (Tokenizer), 'Парсер' (Parser), 'Препроцессор' (Preprocessor), 'Компилятор' (Compiler), 'Ассемблер' (Assembler), 'Линковщик' (Linker), and finally 'Операционная система' (Operating system). The operating system passes a final note back to the 'я' character. The last panel shows the 'я' character looking furiously at this note, which reads 'segmentation fault'. The meme humorously captures the frustrating abstraction of the compilation and execution process, where code copied from the internet goes through dozens of invisible steps, only to fail with a cryptic, low-level memory error, leaving the developer with the daunting task of debugging

A segmentation fault is the compiler's way of saying it has successfully passed the bug from its jurisdiction to the operating system's, which has now made it your problem again
Segfault debugging is the purest supply-chain audit: tokenizer, compiler, linker, even the kernel all sign off “not it,” and the only artifact that makes the round-trip is your undefined behaviour
After 20 years in this industry, I've learned that the build pipeline is just an elaborate game of telephone where everyone correctly repeats what they heard, but nobody bothered to check if the original message was "Hello World" or a null pointer wearing a trench coat
After your code survives the gauntlet of static analysis, tokenization, parsing, preprocessing, compilation, assembly, and linking - each layer dutifully passing it along like a game of telephone through the entire toolchain - the OS finally delivers the punchline: segmentation fault. It's the universe's way of reminding you that all those intermediate representations were just elaborate foreplay before the inevitable core dump. At least you can tell the PM it compiled successfully

In the toolchain blame graph, everything is deterministic until the kernel returns SIGSEGV - turns out StackOverflow isn’t a memory manager
The C toolchain is great at distributed consensus - for blame: tokenizer, parser, compiler, linker all LGTM, and the OS enforces it with SIGSEGV
