0004 Subject: [PATCH 36/46] Check if we reached the end of Iterator
0005
0006 After the first iteration typeToRecognizerEnd can hold a value which has
0007 been removed from m_recognizers. So, the next iteration may be checking
0008 against the previously valid value and pass the check despite
0009 typeToRecognizerIterator pointing to end().
