You want to set a watchpoint. This is a conditional breakpoint which is
activated only when the associated condition is true. To add a watchpoint,
type 'w expr' in the debugger where expr is the expression which must be true
in order for the watchpoint to be activated. In your case, type 'w $i == 10'.
