--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. The ICE is new in GCC 16 but this has been rejected always it seems.
Reduced testcase:
```
int globalCounter = 0;
template<int=1>
void inline_invoke() {
int &counterRef = globalCounter;
auto lamda = []() { counterRef++; };
}
```
The non-template one was fixed for GCC 8.
