No it doesn't. It just states there was an assert because of invalid pointer. A debugger will give you an exact sequence of calls that caused the error.

Maybe does vector of vector need a my own destructor?
Don't guess. std::vector class works for many other people so it will work for you too without modifications. There is an error in your application somewhere, most probably a pointer-based one, so you just have to take a debugger and find it. Knowing a part of code that triggered the assert is not enough if you don't know what (which object and where, in what conditions) called the code. Getting a stack trace will answer that question.

I just don't know why are you defending yourself from using a debugger...
