c++ actions

[George]

Hi all,

 

I meet a problem (the code crashed) when I try to combine bison/flex with actions that are written in c++. .

Especially, when the (geometry) input file contains too many nodes the code crashes inside the vector<int> vnode.I cannot imagine what it is wrong.

Here, is a typical example:

 

Thank in advance.

 

 

// file: parse.y

%{

#include <vector>

#include "node" // user defined class (in c++)

NODE    node;

std::vector<int> vnode;

%}

%token <ival>    yyINTEGER

%token                yyNODE

%%

// GridPoints:

RB_Points:    RB_NODE { vnode.push_back( node.getID() );}

;

// node:

RB_NODE:    yyNODE    yyINTEGER {    assert(fprintf(yyout,"\tID\t= %d\n",$2) );    node.setID( $2 );}

;
