[antlr-interest] Internal error when generating grammar with 3.1b (ANTLRWorks 1.2b5)

[Gikas Gikas]

Hi all,

I have no clue what¹s causing this error ­ seems like a bug... Anyone has
seen this before?  
The grammar checks fine with ANTLRWorks Grammar -> Check Grammar.

[14:50:34] error(10):  internal error:
