I see nothing wrong with how you assign packet structures or accessing them, I think there is something wrong with how you save/display them. What is 'pktFeatures'? I guess it has to be a global variable because I do not see you defining/declaring it anywhere in the code snippet. Should not use global variables in critical parts like this because they can not be put into registers, meaning code is not going to be anywhere as fast as with local variables, also your code automatically is not thread/signal safe.
