running the failing command with -save-temps shows that sahf isused here:

.LM312:
    fprem
    fnstsw  %ax
    sahf
    jp  .L103
    fstp    %st(1)
    fstpl   -56(%rbp)
    movsd   -56(%rbp), %xmm1
    ucomisd %xmm1, %xmm1
    jp  .L109
    jne .L109


adding -v confirms that /usr/sfw/bin/gas is being used as the assembler, not
some other as
