Merged to 'seen', pushed the result out, and saw this:

  https://github.com/git/git/actions/runs/33429987759/job/99612809093#step:10:1391

It seems that it is reproducible locally with the variable settings
stolen from ci/run-build-and-tests.sh, i.e.,

    $ bash
    sh-5.3$ export OPENSSL_SHA1_UNSAFE=YesPlease
    sh-5.3$ export GIT_TEST_SPLIT_INDEX=yes
    sh-5.3$ export GIT_TEST_FULL_IN_PACK_ARRAY=true
    sh-5.3$ export GIT_TEST_OE_SIZE=10
    sh-5.3$ export GIT_TEST_OE_DELTA_SIZE=5
    sh-5.3$ export GIT_TEST_COMMIT_GRAPH=1
    sh-5.3$ export GIT_TEST_COMMIT_GRAPH_CHANGED_PATHS=1
    sh-5.3$ export GIT_TEST_MULTI_PACK_INDEX=1
    sh-5.3$ export GIT_TEST_MULTI_PACK_INDEX_WRITE_INCREMENTAL=1
    sh-5.3$ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master
    sh-5.3$ export GIT_TEST_NO_WRITE_REV_INDEX=1
    sh-5.3$ export GIT_TEST_CHECKOUT_WORKERS=2
    sh-5.3$ export GIT_TEST_PACK_USE_BITMAP_BOUNDARY_TRAVERSAL=1
    sh-5.3$ make T='t8020*' test

and it does reproduce when the topic is tested standalone (I've kept
the base that I have used to queue the previous iteration,
41365c2a9b The 4th batch for Git 2.56).

Ejected out of 'seen' for now.
