Subject: [Bug libstdc++/98842] optional's spaceship operations generates wrong code when operator== is not present
Date: Thu, 28 Mar 2024 11:24:31 +0000 [thread overview]
Message-ID: <bug-98842-4-GZiRP0zTeY@http.gcc.gnu.org/bugzilla/> (raw)
In-Reply-To: <bug-98842-4@http.gcc.gnu.org/bugzilla/>

--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> ---
(In reply to GCC Commits from comment #3)
> Adding that constrain completely breaks std::optional comparisons,
> because it causes constraint recursion. To avoid that, an additional
> check that U is not a specialization of std::optional is needed. That
> appears to be a defect in the standard and should be reported to LWG.
For the record, that is https://cplusplus.github.io/LWG/issue3566
