LEA (load effective address) just computes the address of the operand, it does not actually dereference it. Most of the time, it's just doing a calculation like a combined multiply-and-add for, say, array indexing. In this case, it's doing a simple numeric subtraction: leal -4(%ebp), %eax just assigns to the %eax
