When RenameFunction::RenameFunction(const TString& oldFunctionName, const TString& newFunctionName) is called from TCompiler::rewriteCSSShader(TIntermNode*), references to the temporaries oldFunctionName and newFunctionName are stored as mOldFunctionName and mNewFunctionName. This results in undefined behaviour in visitAggregate.

Possible fix in RenameFunction.h:
 private:
-    const TString& mOldFunctionName;
+    const TString mOldFunctionName;
-    const TString& mNewFunctionName;
+    const TString mNewFunctionName;
