code seems sane too
_Z1fv:
.LFB100:
        subq    $8, %rsp
.LCFI0:
        movl    $128, %edi
        call    _Znwm
        movq    %rax, %rdx
        movl    $16, %ecx
        xorl    %eax, %eax
        movq    %rdx, %rdi
        rep stosq
        movq    $_ZTV17virtual_reference+16, (%rdx)
        addq    $8, %rsp
.LCFI1:
        ret
.LFE100:

so probably solved.
