[antlr-interest] Strange bug in ANTLR version higher than 3.1.2

[FranklinChen at cmu.edu]

As in my README file that was attached:

Output from version 3.1.1/3.1.2:

tree = (TIER (WORD a (PHO 0)) (WORD b (PHO 1)) (WORD c (PHO 2)) (WORD d (PHO 3)))

Output from version 3.1.3/3.2:

tree = (TIER (WORD a (PHO 0)) (WORD b (PHO 1)) (WORD c (PHO 2)) (WORD d (PHO 3)))
ExprTreeParser.g: node from line 1:12 mismatched tree node: PHO
expecting <UP>
