Comment 1 for bug 1962789

A brief update:

I can also reproducee the crash on Ubuntu 21.10 / e2fsck 1.46.3:

# e2fsck -v -z e2fsck.undofile.2022-03-20 /dev/mapper/md125_crypt
e2fsck 1.46.3 (27-Jul-2021)
Overwriting existing filesystem; this can be undone using the command:
    e2undo e2fsck.undofile.2022-03-20 /dev/mapper/md125_crypt

ext2fs_check_desc: Corrupt group descriptor: bad block for block bitmap
e2fsck: Group descriptors look bad... trying backup blocks...

If I run "e2fsck -v /dev/mapper/md125_crypt" (without -z), e2fsck 1.46.3 does not crash.
