--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Reduced:
#include <compare>
template<typename T, typename U>
constexpr std::weak_ordering
cmp(T e, U f)
{
return e <=> f;
}
auto o = cmp(1, 2);
wo.cc:10:18: in 'constexpr' expansion of 'cmp<int, int>(1, 2)'
wo.cc:10:18: internal compiler error: in cxx_eval_constant_expression, at
cp/constexpr.c:5123
10 | auto o = cmp(1, 2);
| ^
Related to converting the strong_ordering result of <=> to weak_ordering?
