----------------------------------------

ok thanks,  looks like I can duplicate this compile failure on my mac as well (which has a different flex than my linux box).  I'll make a new patch shortly.

> Valgrind reports a leak coming from the flex parser generated code.
> The flex-generated lexer allocates memory to use for its state stack.  Examining this code it is clear that once allocated, the stack is never freed.  Since I cannot easily replace flex code, I inserted the code to free the stack as a lexer rule.  
> Valgrind is happy with the result.
