--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
You mean like this one?
/usr/include/c++/11/optional:440: constexpr _Tp& std::_Optional_base_impl<_Tp,
_Dp>::_M_get() [with _Tp = int; _Dp = std::_Optional_base<int, true, true>]:
Assertion 'this->_M_is_engaged()' failed.
Aborted (core dumped)
It's been there since r248099 more than four years ago.
Just compile with -D_GLIBCXX_ASSERTIONS
