--- Comment #17 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The difference is due to this change in std::call_once
- __once_callable = std::__addressof(__callable); // NOLINT: PR 82481
- __once_call = []{ (*(decltype(__callable)*)__once_callable)(); };
+ once_flag::_Prepare_execution __exec(__callable);
But I don't know why.
