--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
If you compile with -D_GLIBCXX_ASSERTIONS then there is a runtime check:

/home/jwakely/gcc/11/include/c++/11.0.0/bits/stl_iterator_base_funcs.h:151:
constexpr void std::__advance(_InputIterator&, _Distance,
std::input_iterator_tag) [with _InputIterator = std::_Fwd_list_iterator<int>;
_Distance = long int]: Assertion '__n >= 0' failed.
Aborted (core dumped)
