segfault with git rebase --abort

git rebase -i

git rebase --abort # boom

git status only shows changes to be committed
I can mail or upload the git archive, that would be 230MB

git fsck;git repack;git prune;git gc does not help

Happens with git 2.39 and with latest git commit 11c821f2f2a31e70fb5cc449f9a29401c333aad2, compiled with -g -O0
