[antlr-interest] [C] scope pop function

[Jim Idle]

Looks like a bug in the stringtemplates that were changed for ST4 in this
version of ANTLR. You might want to try 4.2 until I can fix this.

Subject: [antlr-interest] [C] scope pop function

Hi all,

When I try to use a scope in my tree parser, I encounter an error in the
generated code.
The scope pop function is generated as follow (I removed the generated
comments to make it more readable) :

void pmyparser_tree_myScopePop(pmyparser_tree ctx) {
    if    (SCOPE_TOP(myScope)->free != NULL)
    {
        SCOPE_TOP(myScope)->free(SCOPE_TOP(myScope));
    }

    ctx->pmyparser_tree_myScopeStack_limit--;
    SCOPE_TOP(myScope) =
(pmyparser_tree_myScope_SCOPE)(ctx->pmyparser_tree_myScopeStack->get(ctx->
,
ctx->pmyparser_tree_myScopeStack_limit - 1));
}

As you can see in the last function line, the first parameter of the get
function call is missing a field descriptor: "get(ctx->, ...)".
Is there something wrong in my parser to provoque this issue? Is this a
known issue of ANTLR 3.4?

The tree parser generator outputs the following messages that I don't
really understand :

ASTTreeParser.stg 321:25: anonymous template has 0 arg(s) but mapped
across
