[antlr-interest] Problem when using scopes in C with ANTLR 3.4

[Iron Bug]

Greetings, everybody!

I have found a problem with C code generation in ANTLR 3.4 (I used pure
3.4 from standard downloads).

A simple grammar (just to show the problem):

//////////////////////////////////////////////////////////////////////
grammar test;

options
{
  language		= C;
}

scope GlobalScope
{
	int scope;
}

@header 
{
#include "antlr3.h"
}

command 
scope GlobalScope;
@init
{
	$GlobalScope::scope = 10;
}
	:
	VALUE	
	;

VALUE
	:	('0'..'9')+ 
	;
	
/////////////////////////////////////////////////////////////////
The grammar produces code with error in generated file testParser.c,
line 321:

SCOPE_TOP(GlobalScope) =
(ptestParser_GlobalScope_SCOPE)(ctx->ptestParser_GlobalScopeStack->get(ctx->, ctx->ptestParser_GlobalScopeStack_limit - 1));

(the ctx with reference to nowhere in the first parameter of get()).
It goes all right in 3.3, though. Have I missed some changes in 3.4 or
is this a bug?
