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]

    This almost got chucked as spam but martyb thought we could make a decent discussion out of it. Don't look for him to go pushing out anything they submit though.

    Yeah. When I saw it in the queue, I wondered if it would make the cut.
    It has stirred some interesting discussion, so it appears that the proper choice was made.

    What I was hoping to see was the names of some tools in use.
    Comparisons by folks who had tried multiple apps would be especially interesting.

    Licenses (FOSS|proprietary) and license costs would add a dimension as well.
    (Envying the larger userbase of the other site here.)

    The Wikipedia page linked in TFS has an External links section, but I was hoping to see a link to a "Comparison of..." Wikipedia page there.
