I am afraid that this might not be correct, as t0410.27 experienced a
segmentation fault (see
https://github.com/git/git/pull/1018/checks?check_run_id=2511749719#step:5:2845
for the full details):
Thanks for spotting that. On further investigation this looks like a
preexisting issue on seen (my github PR was based on seen - in hindsight
that was probably not a good idea) - here's a CI run from seen this
morning exhibiting the same failure:
https://github.com/git/git/runs/2515095446?check_suite_focus=true
To gain more confidence, I've rebased my patch onto next, and I no
longer hit any CI failures:
https://github.com/ahunt/git/runs/2515309312?check_suite_focus=true
(I ran this on my fork because changing the base branch appears to have
confused the PR's CI configuration.)
Nevertheless, I was still curious about what might be causing the
failure in the first place: it appears to only happen in CI with gcc on
Linux, and I was not able to repro on my machine using (tested with
gcc-7.5 and gcc-10, with seen from this morning):
make CC=gcc-10 T=t0410-partial-clone.sh test
I'm guessing that understanding this failure might require the help of
someone with an Ubuntu install to debug (unless there's some easy way of
using Github's Actions to run a bisect)?
