            Bug ID: 96905
           Summary: ICE with consteval function: internal compiler error:
                    in cp_gimplify_expr, at cp/cp-gimplify.c:827
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: redi at gcc dot gnu.org
  Target Milestone: ---

template<typename Rep>
struct duration
{
  static consteval int
  gcd(int m, int n) noexcept
  {
    while (m != 0 && n != 0)
    {
      int rem = m % n;
      m = n;
      n = rem;
    }
    return m + n;
  }
};

template class duration<int>;

Compiled with -std=gnu++20 this ICEs:

ice.C: In static member function 'static consteval int duration<Rep>::gcd(int,
int) [with Rep = int]':
