c++ - Vector iterator not dereferencable? -

i'm getting error code:

for(std::vector<aguitimedevent*>::iterator = timedevents.begin();     != timedevents.end();) {     if((*it)->expired())     {         (*it)->timedeventcallback();         delete (*it);          = timedevents.erase(it);     }     else         it++; } 

what problem?

the timed event pushes new 1 in when callback called, might

thanks

if looping through vector , callback function causes vector added to, iterators vector may invalidated including loop variable it.

in case (where callback modifies vector) better off using index loop variable.

you need thorough analysis of design make sure aren't going create unexpected infinite loops.

e.g.

for(std::vector<aguitimedevent*>::size_type n = 0;     n < timedevents.size();) {     if(timedevents[n]->expired())     {         timedevents[n]->timedeventcallback();         delete timedevents[n];          timedevents.erase(timedevents.begin() + n);     }     else         n++; }
