Pointer being freed was not allocated?

Hi!
Why is my game crashing and comes up with this argument?

After some time i figured out where it was coming from and now i know for sure that it is coming from this code here:

 case 2:
                
                while (true) {
                    
                    int l= RandomHelper::random_int(2, 32);
                    
                    //Check whether the current poss has been used in the current quiz or not
                    bool hasBeenUsed = false;
                    
                    if (usedStrings.size() >= 1) {
                        
                        for (int i = 0; i < usedStrings.size(); i++) {
                            
                            if (usedStrings.at(i) == std::get<2>(getItemSet(l))) {
                                
                                hasBeenUsed = true;
                                
                            }
                        }
                    }
                    if (hasBeenUsed == false) {
                        std::string naming = (std::string)std::get<3>(getChampSet(l));
                       usedStrings.push_back(naming); return naming;
                }
                }

Btw the initialization of usedStrings =

static std::vector<std::string> usedStrings;

?

Thanks!!!<33

I’m not sure but try doing a usedStrings.clear() before pushing anything into the vector.

nichlaspro132 · December 4, 2015, 2:03pm

But i have to store all the strings that i have used before in the vector…And clear kinda removes everything so the code can’t check whether the string has been used before right?

Thanks anyway, i appreciate ur time!

In recent Xcodes there’s a tool called Address Sanitizer, here’s some info and how to enable it: http://useyourloaf.com/blog/using-the-address-sanitizer.html

I’m pretty sure you will easily find a problem in your code with it and highly recommend turning it on permanently in debug builds

TheDevil · December 4, 2015, 5:54pm

What I meant is as soon as you declare the variable for the vector,clear it on the next line.
Like this:
static std::vectorstd::string usedStrings;
usedStrings.clear();

Uh! Something happened! #oneMoreThingLearned
BUT it got kinda scary when all this text occurred, how to know what it is referring to, THANKS!<3:

Already tried but thanks for the thought!

ASan gives you three stacktraces in this case:

where you are attemting to double free
where the memory was freed
where the memory was allocated

you should go down each of the traces and check out corresponding lines in your program.

QuizGraphic::getRandObj(std::1::basic_string1::char_traits, std::__1::allocator >) QuizGraphic.cpp:138 - something is messed up in this line I guess.

WOW COOL! So it is this line but what is wrong with that???

     if (usedStrings.at(i) == std::get<2>(getItemSet(l)))

Help appreciated x10000!

Well, it’s hard to say what’s wrong with just one line of code, but here are a few moments:

Using .at in a loop makes no sense, you control the index
You probably want a struct or class instead of tuple

Got it fixed! Thanks for all ! God bless
