>Description:
By mistake I created an awk script with unfinite loop
and nawk segfaults running it. I've found this under Linux but
I think it will segfault on any platform including NetBSD.

nawk is from NetBSD CVS 20071026 (wip/netbsd-awk package).

#!/usr/pkg/bin/nbawk -f

function rec2 (num){
        rec2(num+1)
}

BEGIN {
        rec2(0)
        exit 77
}
