Memcheck generally has a low false positive rate (though I am little biased). You need to read the source and decide based on that. A+ Paul " the main reason why it looks like a false positive is that I've had these valgrind warnings ... since probably ever, but it was never causing issues. I cannot tell from the sources if there is anything wrong, so I am better asking here. Thanks! Zdenek " "
