[antlr-interest] Doubt Regarding TreeWalker Error!!

[mark twain]

Hi,

I was trying to run one of the example code <simplecTreeParser> and when I
execute the following command :

 treePsr->program(treePsr);

I am getting the following error :
=================================
./input(1)  : error 10 : Unexpected node, at offset 0, near <missing
<invalid>> : Missing <invalid>
./input(2)  : error 10 : Unexpected node, at offset 0, near <missing
<invalid>> : Missing <invalid>
 =================================

My input file is :

int x;

void bar(int x);

int foo(int y, char d) {
  int i;
  for (i=0; i<3; i=i+1) {
    x=3;
    y=5;
  }
}
=========================================

I have not made any changes from example code and tried to run using C
runtime library(antlr-3.1b2).

Any pointers what I am missing.

Cheers:)
