When a lexer rule/pattern is shared among multiple lexer states, CookCC erroneously report unreachable statements. See http://code.google.com/p/cookcc/source/browse/trunk/tests/java/lexer/states/tight.xcc It is actually due to the fact that DFA states from another lexer state have been re-used. A potential solution to this problem is to eliminate such re-use, resulting in slightly increased number of DFA states. |

Fixed by stop sharing dfa state sets. Resulting slight increase in terms of number of dfa states. See http://code.google.com/p/cookcc/source/detail?r=612
Status: Fixed
