--- Comment #3 from Lars Gullik Bjønnes <larsbj at gullik dot org> ---
I cannot send you the unreduced preprocessed code and I have failed at creating
a small
snippet that produces the error.
This is the compiler output though.
Something might be gleaned from that.
In function ‘constexpr decltype (::new(void*(0)) _Tp) std::construct_at(_Tp*,
_Args&& ...) [with _Tp = unsigned int; _Args = {unsigned int}]’,
inlined from ‘static constexpr void
std::allocator_traits<std::allocator<_CharT> >::construct(allocator_type&,
_Up*, _Args&& ...) [with _Up = unsigned int; _Args = {unsigned int}; _Tp =
unsigned int]’ at /usr/include/c++/12/bits/alloc_traits.h:518:21,
