I've run the code on Windows XP with gawk-4.1.0 from ezwinports. It 
prints some stuff and ends with (long line, may be wrapped):

gawk: _main.gwk:2152: fatal: unwind_stack: unexpected type `Node_var_array'
Program exited normally with exit value: 2

The debugger shows that the last executed statements, still in the BEGIN 
rule, are a call:

    _fatal("out of UID")

to:

    func _fatal(t,d, A) {
        if ( _ERRLOG_FF ) {
            A["TYPE"]="FATAL"; A["TEXT"]=t
            _log(A,d)
        }
        if ( !d ) exit
    }

I.e., a function that expects an array as a third argument is called 
with just one argument, and forces an exit before returning. This is 
more or less consistent with the given error message.

I've attempted to reproduce the fatal error with a minimal sample code, 
without success. Everything I tested worked OK.

Hope this helps. Regards,
