Then add the `tok::star` case too:
```diff
--- a/clang/lib/Format/UnwrappedLineParser.cpp
+++ b/clang/lib/Format/UnwrappedLineParser.cpp
@@ -2741,6 +2741,8 @@ bool UnwrappedLineParser::parseParens(TokenType AmpAmpTokenType,
     case tok::kw_requires:
       parseRequiresExpression();
       break;
+    case tok::star:
+    case tok::amp:
     case tok::ampamp:
       if (AmpAmpTokenType != TT_Unknown)
         FormatTok->setFinalizedType(AmpAmpTokenType);
```
I prefer plugging the hole above because that's the direct cause that unlike `&&`, `*` and `&` are not annotated as `TT_PointerOrReference`.
