Works for me:
jh@evans:/abuild/jh/trunk-3/build-inst7> /abuild/jh/trunk-install/bin/g++  -O2
t.C -flto -c
jh@evans:/abuild/jh/trunk-3/build-inst7> /abuild/jh/trunk-install/bin/g++  -O2
t.o -flto --save-temps
[Leaving LTRANS /tmp/ccy4OrZL.args]
[Leaving LTRANS /tmp/ccFrEQBZ.ltrans.out]
[Leaving LTRANS /tmp/ccMy8uNk.args]
[Leaving LTRANS /tmp/ccFrEQBZ.ltrans0.o]
jh@evans:/abuild/jh/trunk-3/build-inst7> more *ltrans*s
        .file   "ccFrEQBZ.ltrans0.o"
        .section        .text.startup,"ax",@progbits
        .p2align 4,,15
        .globl  main
        .type   main, @function
main:
.LFB0:
        .cfi_startproc
        xorl    %eax, %eax
        ret
        .cfi_endproc
.LFE0:
        .size   main, .-main
        .ident  "GCC: (GNU) 4.8.0 20120324 (experimental)"
        .section        .note.GNU-stack,"",@progbits

So this is all about -O0?
At -O0 I get:
       .local  _ZZN1C1mEvE1d.local.1.2356
        .comm   _ZZN1C1mEvE1d.local.1.2356,8,8
