--- Comment #3 from Antony Polukhin <antoshkka at gmail dot com> ---
Diagnostic with trunk (GCC-16) is
```
<source>: In function 'void sample(my_vector&, my_iterator)':
<source>:5:19: error: cannot convert 'my_iterator' to 'int'
5 | vec.push_back(it);
| ^~
| |
| my_iterator
<source>:1:35: note: initializing argument 1 of 'void
my_vector::push_back(int)'
1 | struct my_vector { void push_back(int); };
| ^~~
Compiler returned: 1
```
but he fix-it hint "possible fix: dereference with '*'" is still missing
