today I had the unpleasent experience to receive [1] to a lot of PDF files
which seem to contain some reports of the Klocwork static code analysis tool.
Most of the stuff was nonsense about memory/resource leaks (even when it
stored in some kind of structure one line before). I gathered the only
interesting portions and prepared some patches for them.

The last two patches are actually not really bug fixes but are about code
which completely killed the static analyzer. I didn't like the code in
the last patch (looked to complex for something relatively easy) and thus
I've just replaced it.

WARNING: these things were only compile tested

Kind regards,

[1] not unpleasent due to some issue reports. But going through several
    hundred false positives wasn't my goal for today. Someone at seems to
    get paid by false-positives which this Klocworks analyzer produces
    (and there are really some braindead ones - even clang's static analyzer
    looks like a genius against some of these reports)
