[hjl@gnu-6 880]$ rm x.s

        .file   "x.c"
        .text
        .p2align 4,,15
.globl main
        .type   main, @function
main:
        pushl   %ebp
        movl    %esp, %ebp
        subl    $8, %esp
        leave
        jmp     foo

The stack isn't aligned to 16byte.
        .size   main, .-main
