2821 needed. But we don't have the index for this hash-table entry. We
2822 rely here on that the current entry is the first hash-entry with NULL,

2824 entry is a linear operation on the number of symbols in this input
2825 file, and this function should take constant time, so that's not good
2826 too. Only comfort is that DataLabel references should only be found in
