Indeed, I get a segfault at this point. When debugging, I see that
vector<T>::operator[] is really executed with an out-of-bound index.
And this really dereference and invalid memory location. If you look
into MSVC header you find something like:
reference operator[](size_type _Pos)
{ // subscript mutable sequence
return (*(_Myfirst + _Pos));
}
