Commencez par reproduire repository.Diff.Compare< Patch >(commitB.Tree, commitA.Tree) avec les commits indiqués et examinez la trace de la pile à travers Diff.Compare et LibGit2Sharp.Patch. Inspectez la manière dont le chemin dupliqué tools/firmware-utils/src/bcm_tag.h est traité ; c’est terminé lorsque la comparaison renvoie un patch au lieu de lever l’exception de clé dupliquée.
