Knowing C/C++, I more or less guessed what's happening (uninitialized variable) early in the blog post.

It blows my mind that the languages allow you to leave variables uninitialized which has caused countless bugs (including production bugs that I have seen first hand), and you often need to rely on additional compiler flags or static analysis tools/valgrind etc to catch them. Even though newer languages often use a different solution (default zero value or must initialize a variable before use), people still go back to C/C++ all the time.
