The issue can be reproduced on godbolt with an asserts build but is too large for the short link generator to handle it.

Endilll commented 5 months ago

Confirmed on 19.0 and 18.1.0: https://godbolt.org/z/qaxGa7ocs Appears to be a regression in Clang 15. It also reminds me of #88077 Reduced by me and C-Reduce:

struct get_scheduler_t {
  void operator()();
};

template <class _Ty>
struct __box {
  [[no_unique_address]] _Ty __value;
};

struct __sexpr {
  __box<get_scheduler_t> __impl_;
};

void get_scheduler_t::operator()() {
  __sexpr{};
}
