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/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
