I'm concerned that this is a sign that the approach I suggested does not actually work everywhere. I.e., could this be a case where we have some non-promisor object that points to a sub-object that is reachable from the promisor pack, but not a direct tip? Before your patch we'd consider that sub-object a promisor (because we enumerate all of the graph that we do have and mark each such object), but afterwards we would not. And I wonder if that confuses pack-objects. Though I think it would confuse it in the _opposite_ direction. I.e., using --exclude-promisor-objects would count such an object as not-a-promisor and would be more inclined to include it in the new pack. It is curious that this only turns up with GIT_TEST_COMMIT_GRAPH=1, too. It seems like any such problem ought to be independent of that. Puzzling... -Peff
