[ad_1] Here is one issue: void WaveTableManager::insert(WaveTable * WT,int position) { if (wtvector.size()<=position) wtvector.resize(position); wtvector[position]=WT; // < — Out of bounds access } When you call resize(), the upper bound is vector::size()-1. Since position is the new size of the vector, what you probably want is this: wtvector[position – 1] = WT; 5 [ad_2] solved … Read more
