--- Comment #20 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
This PR has reappeared after r205679 with warnings of the kind

warning: DWARFDebugInfoEntry::AppendDependants() -- check on this item
TAG_namelist_item: attr =  AT_namelist_item  form = FORM_ref4

They are silenced with the following change of the regexp added at r167683:

I hope this change will survive any fix for pr59438!
