    .type    _ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__, @object
    .size    _ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__, 11

stage3:

    .align    2
    .type    _ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__, @object
    .size    _ZZN19ref_always_accessedclEP11mem_ref_locE12__FUNCTION__, 12

Be aware of the additional blank in the string. This does not happen when
disabling LRA for bootstrap.
