--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Clang rejects it too:
```
<source>:7:37: error: no viable overloaded '='
7 | const_cast<domain &>(d) = other.d;
| ~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~
<source>:7:37: note: type 'domain' (aka 'ring<int>') is incomplete
7 | const_cast<domain &>(d) = other.d;
| ~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~
```
TO workaround the broken code for GCC 15+, you can use -Wno-error=template-body
. But the code is definitely broken because there is no viable `operator =`
since domain (aka ring<int>) is non-dependent type and is incomplete at the
time you try to use `operator =`.
