I can confirm it with trunk version for -O0, too.

Issue is that there seems to be a wrong-code generation bug for O0 and
read-only section data.

...
        movq    aa.2567(%rip), %rax
        movq    %rax, %rdx
        leaq    .LC0(%rip), %rcx
        call    printf
...

...
        .data
        .align 8
aa.2567:
        .section .rdata,"dr"
.LC1:
        .ascii "foo\0"
        .quad   .LC1+1
...

The aa.2567 label is emitted in data, but its definition in .rdata
