--- Comment #2 from Sam James <sjames at gcc dot gnu.org> ---
(In reply to Jakub Jelinek from comment #1)
> Is KDE Plasma built with -std=gnu++20 or -std=gnu++17?
-std=gnu++20
> Perhaps as a workaround -fno-range-for-ext-temps option could help.
> If it is built with -std=c++23/gnu++23 or later, that won't work though.
Let me try.
Meanwhile, here's a backtrace for completeness:
