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]

    I met a kein faschist in 1990, that was his statement about the Neo Nazis then (27 years ago) "when you see a skinhead, you must punch them in the face."

    So, while I agree that skinheads were (still are?) needlessly violent idiots, punching them in the face on sight doesn't seem to be accomplishing the goal of reducing violence and prejudice in the world.

    Not so long ago, I read an article that said protests are counter-productive, giving them a higher profile and bolstering their recruitment efforts.

    ...but it must give a warm feeling inside when you e.g. dump feces on them and the Reactionary forces who would protect them. [google.com]
