Bug#820086: antlr3: v3.5 breaks existing grammars

[olivier sallou]

Package: antlr3
Version: 3.5.2-4
Severity: normal

Dear Maintainer,

   * What led up to the situation?
     switch version to 3.5 from 3.2
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     Logol package fails to build. Logol uses antlr to generate some
grammar files. With v3.2, package worked. When upgraded to 3.5, the
generated grammar (parser/lexer) is different with a different behaviour.

I cannot give a specific test, as my grammar rules are quite complex, and
after investigation, I still cannot find the root cause, except the antlr
implication.
It seems this releases introduced new parsing behavior that affects
existing grammars.
