           Summary: crash on AnalysisBasedWarnings
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal

The test:
------------
struct nsCString {
  ~nsCString();
};
struct nsPromiseFlatCString : public nsCString {
  nsPromiseFlatCString( const nsCString& str );
};
int SetStringProperty(const nsCString& aKey) {
  const nsCString& flatKey = nsPromiseFlatCString(aKey);
}
------------

produces a segmentation fault:

$ clang -cc1 -Werror=return-type nsPersistentProperties.ii
