Can you try the mainline of gcc where the basic block reordering has been rewritten and now it 
produces:
.L972:  
        movl    (%edi), %eax
        addl    $4, %ebp
        movl    %eax, 636(%esp)
.L340:
#APP
        #question_branch
#NO_APP 
        movl    -4(%ebp), %eax
        jmp     *%eax

Which looks correct.
