I come, hat in hand, with a bug-fix for a bug that I wrote. I just happened to discover this issue while playing around with turning the commit-graph on by default and stumbled into this warning.
Please see the commit message for full details, but putting octopus merges in a tip commit-graph file in the incremental format [1] would cause the file to not load because Git thinks the base commit-graphs do not have the right hashes. It is very likely that a more careful patch would allow this warning to become an error during git commit-graph verify, but I wanted to minimize the change for this quick bug fix.
