Hello, I encountered the following bug and filled out the template provided with `git bugreport` below. Kind Regards, Jonas Kittner Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue. What did you do before the bug happened? (Steps to reproduce your issue) In the interactive prompt I changed `pick` to `reword`, saved and closed the prompt. Commands to repoduce see below ``` root@135b2edea980:/# git init bug Initialized empty Git repository in /bug/.git/ root@135b2edea980:/# cd bug/ root@135b2edea980:/bug# touch foo root@135b2edea980:/bug# git add . root@135b2edea980:/bug# git commit -m "foo" [master (root-commit) 8fef261] foo 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 foo root@135b2edea980:/bug# touch bar root@135b2edea980:/bug# git add . root@135b2edea980:/bug# git commit -m "bar" [master 79a46e6] bar 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 bar root@135b2edea980:/bug# git log --oneline 79a46e6 (HEAD -> master) bar 8fef261 foo root@135b2edea980:/bug# git rebase --interactive --committer-date-is-author-date 8fef261 BUG: sequencer.c:921: GIT_AUTHOR_DATE missing from author script Aborted (core dumped) root@135b2edea980:/bug# git --version git version 2.33.1 ``` What did you expect to happen? (Expected behavior) I expected to be able to reword the commit message like without passing the `--committer-date-is-author-date` argument. What happened instead? (Actual behavior) segfault: `BUG: sequencer.c:921: GIT_AUTHOR_DATE missing from author script` What's different between what you expected and what actually happened? wouldn't expect a segfault, but the option to be able to edit the commit message Anything else you want to add: This was inside an ubuntu focal docker container, git was installed via the ppa ` ppa:git-core/ppa` https://github.com/git/git/commit/7573cec52c0274ceb166c425be4288f6b3103d6f#d iff-0e574dc9087fc7831bbc1403545a8561f08869576c1ccc4146aa276146ff9777R888-R88 9 this seems to be not the case and needs to be handled differently I guess?
