After you overflow the buffer, all bets are off. It can but doesn't have to
overwrite unrelated variables around, and which exact depends on the
optimization flags, architecture and how exactly the compiler decides to lay
stuff out.
User -fsanitize=address to detect such buffer overflows, fix them and then
ubsan behavior will be sane.
