I have bisected this on upstream's Git, and the failure-inducing change
is apparently 47fee2ef

<http://git.kernel.org/cgit/fs/ext2/e2fsprogs.git/commit/?h=maint&id=47fee2ef6a23ae06f680336ffde57caa64604a4c>

I reported this in greater detail to the authors/reviewers of the patch.

Let's see what we get.  For -current/-toolchain and decke_at_ I consider
this closed.

Thanks to Antoine for setting me on the right track.

Cheers,
Matthias
