Even worse, they may end up in a register that the optimized has =20
decided can also be used for some other local variable that doesn't =20
have the same lifetime.  So even if the local variable is in scope and =20
viewable, it may contain a value that belongs to some other variable.  =20
(more frequently, debuggers will simply claim that the variable =20
doesn't exist and can't be seen.)
