I just tried this with the current gcc-2.95 CVS sources and got:


foo:
        pushl %ebp
        movl %esp,%ebp
        movl 8(%ebp),%edx
        incl %edx
        movl %edx,%eax
        jmp .L2
        .p2align 4,,7
.L2:
        movl %ebp,%esp
        popl %ebp
        ret $4


Which appears correct.  I believe one of rth's patches fixed this bug.
