    This is just an robustness enhancement suggestion.

https://github.com/llvm/llvm-project/issues/79748

I triggered this issue and found the solution done in https://github.com/llvm/llvm-project/issues/79748. However, the test cases attached to https://github.com/agozillon/llvm-project/commit/323660ae742aecb524898f956590d599e8869f7f do not include those for reference qualifiers, in addition to cv-qualifiers. As for the completeness consideration, I suggest to add more test cases like:

```c++
void* operator new(size_t bytes) &; //expected-error...
void* operator new(size_t bytes) &&; //expected-error...
```
