Code Analyzer Turned Out to be Smarter Than One of its Creators

I am really astonished by the capabilities of static code analysis. The tool surprised me the other day as it turned out to be smarter and more attentive than I am. I found I must be careful when working with static analysis tools. Code reported by the analyzer often looks fine and I'm tempted to discard the warning as a false positive and move on. I fell into this trap and failed to spot bugs...Even I, one of the PVS-Studio developers.

So, appreciate and use static code analyzers! They will help save your time and nerve cells.

[Ed note: I debated running this story as there was an element of self-promotion (aka Bin Spam), but the submitter has been with the site for a while and has posted informative comments. Besides, I know there have been far too many times when I've seen a compiler complain about some section of my code and I'm thinking there is nothing wrong with it — and then I, finally, see my mistake. Anyone have samples of code where you just knew the compiler or static analyzer was wrong, only to find out otherwise? --martyb]

    What's a "tuner"?

    My god! Was radio that long ago?

    But I was mistaken. The discriminator (demodulator) is after the tuner.

      And you blame Millennials, when truly, Grandpa, it is your own memory that fails you! Do you remember when blacks knew their place? Do you remember when America was a White nation, with a White President, and a White House with a White Dog? And now all we have is an Orange President, with some ex-Commie Bimbo first Lady, and no dog! Why does the president not have a dog? So, yeah, Nazis are totally cool now, until someone threatens to "punch them in the face!" [youtu.be]

      Take it off, white boy, take it off!
