You are adding memory addresses. If you change what $b points to, the add it to $a, the $sum will change. You state : I make a change to hashref $b Did you change the internal content of the hashref, or did you assign a new hashref to $b ? (Thereby changing the memory address) ...it is unhealthy to remain near things that are in the process of blowing up. man page for WARP, by Larry Wall
