runtime error

[wysota]

sorry, maybe I can't understand; jpeg attached previous shows where's the crash;

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...

What do you mean for debugging? (.net has debugger); how I said in first post debugging I can see all program is exectuted correct but on "return 1" it crash(this with what I mena for debugging); it seems to me some problem with destructor of the vector of vector but I don't understand why. Is this below the stack trace you mean?

I attach this small program hoping one more hint.
