The top of the stack always points to 'stack_base + stack_size'. But the stack pointer is decremented before writing to the stack. It means the top byte of the stack is actually 'stack_base + stack_size - 1'. The initialization should also decrement the stack pointer before zero'ing the memory (pre-indexed addressing).
