I'm seeing the exact same problem on one of my filesystems. I noticed that both my filesystem and the one in the original report has the exact same feature flags enabled, including *bigalloc* with a 1MiB cluster size. Could that be the root cause?
Note that my system has no /etc/e2fsck.conf file, and that I have tested e2fsck from e2fsprogs:amd64 1.42.9-3 and 1.42.9-2, e2fsck.static from e2fsck- static:i386 1.42.9-3, and e2fsck.static from e2fsck-static:amd64 1.42.9-3, 1.42.9-1, and 1.42.8-1, all with the same result.
