Yes.  And without optimization enabled, I don't see any reason that the 
compiler should be expected to reuse the stack space; that's an 
optimization.  The compiler might, for example, be able to generate code 
more quickly by using a new stack slot for every variable.  Or, using 
different stack slots, might result in faster code on some machines, 
which is nice even at -O0.
