That is related to .debug_ranges, not .debug_aranges.
E.g. in the int main () { return 0; } case ranges_by_label_in_use is 0, not
surprisingly, we don't emit .debug_ranges in that case.  .debug_ranges is only
needed if some function or lexical block or inlined function doesn't have a
single range, but multiple ones.
