parser stack overflow

[Nosnos]

hi,

I must make a real time parser/lexer (bison/flex), that lex/parse the stdin 
stream.

The parser must work in continuous without stoping.

My first rule was something like that :

frame : FRAME other frame
      | FRAME other
      ;

other : [...]


Of course, i get a stack overflow.

So i want to know how to prevent this ? :

- Maybe with a better set of rules, but I don't know how (precision my file 
come from a sniffer, so the file contains lot a part separate by the work 
frame).
- I thought about having a loop outside the parser that always called yyparse 
...
  the starting rules will be so :
  frame : FRAME other   { return 0;} 
        |               { ERROR ; return -1;}

- ???

Is the second solution a possible way ?
Have you other better suggestion ?

thx a lot
