Perhaps a duplicate of #63139
The following fails to compile with 19.1.0 and current trunk. It works if the argument is a value type instead of reference. Works with GCC.
```
class Foo
{
public:
constexpr static bool foo = true;
};
template <typename T>
int func(T& t)
{
if constexpr (t.foo)
{
return 1;
}
else
{
return 0;
}
}
int main()
{
Foo f;
int i = func(f);
return i;
}
```
