[antlr-interest] ANTLR 3.0b6 Code Generation Issue

[Bert Williams]

If I remove the comment at line 130 of the attached grammar file, ANTLR3.0b6
generates code with the following types of errors:

*	"eregexParser.java": LA12_2 is already defined in expression_term()
at line 1052, column 25 

The error does not occur if the line is commented out.

 

No ANTLR error is generated with either grammar.

 

What's causing this?  Is there a workaround?

 

Bert Williams.
