This should be simple:

I wanted to learn lex & yacc.  So I bought the O'Reilly & Associates 
book.  I begin compiling and linking the examples.  Things are looking 
good and working fine; until, I get to the yacc section in chapter 1.

I have the lex examples coded from Example 1.6 and the yacc examples 
coded from Example 1.7 and 1.8.  I then do:

    flex ch1-05.flex
    byacc ch1-05.byacc
    gcc -c lex.yy.c y.tab.c
    gcc -o ch1-05 lex.yy.o y.tab.o -lfl

Now here is where the problem starts:
I execute ch1-05 and get the attached dump. 8^(

I've also attached the flex and byacc source files.


Does anyone have a solution?
