You need to check that the Decl actually have a name - this might not be the case for an operator, a constructor, etc
```cpp
if(CallLoc.isMacroID() && DiagDecl->getIdentifier()) {
StringRef Name = DiagDecl->getName();
if (Name == "__assert_fail" || ... ) {
....
}
}
```
This is what is causing the test failures
