Expression: cannot increment value-initialized iterator (Error in Debug, but not in Release mode - Visual Studio)

I have the problem that some parts of my code run in the Release mode without a problem, but errors appear in the Debug mode.

Setup: c++ 17 - Visual Studio 2019

To show the difference I wrote a little testcode:

int main()
{
   //Vector containing 20 lists with length of 10 each. Every Element = 10
   std::vector<std::list<int>> test(20, std::list<int>(10,10));

   std::cout << test[6].front() << std::endl; //test if initialization worked

   std::list<int>::iterator test_iter;
   for (test_iter = test[6].begin(); test_iter != test[6].end(); test_iter++)
   {
       std::cout << *test_iter << std::endl;
       test[6].erase(test_iter);
   }
}

In Release it works fine

But in Debug I get this

Does anyone have an idea why there is a difference between the both mode and how I can adjust it, so the Debug mode works fine as well?

Thanks for your help in advance!

The problem is not so much that it doesn't work in debug, as it is that it appears to work in release - the code is equally broken in both, but the debug version of the library has some extra error-checking code.
The error message is a bit cryptic, but what it's trying to say is that you're attempting to increment an iterator that can't be incremented.

This happens because test[6].erase(test_iter); invalidates test_iter, and using it after that is undefined.

erase returns an iterator to the element following the erased element, and you can use this iterator instead of incrementing:

for (test_iter = test[6].begin(); test_iter != test[6].end(); /* empty */)
{
    std::cout << *test_iter << std::endl;
    test_iter = test[6].erase(test_iter);
}
