I can only investigate the state my filesystem is in, I have no idea how the
file ended up being troublesome as it is.

This is an archive (6MB) that contains zstreamdump output and zdb output. The
names are like this:
redo2 - ZoL 0.6.4.2 (GOOD)
redo3 - ZoL 0.6.5.3 unpatched (BAD)
redo4 - ZoL 0.6.5.3 with pull 37 (BAD)
Comparing the dumps, a diff between redo2 and redo4 will show this (and only
this). Quite a few "FREE object" entries that used to be present in the older,
good version have been dropped:

The redo3 dump is not that easily comparable and is quite different.
I created the cloned datasets like this. zfs send was done using the respective
ZoL version; all receives were done on 0.6.5.3, but this is irrelevant. f7dump
is the original uncorrupted dataset.
```
[sr@dumpl ~]$ sudo zfs promote dpool/f7dump
[sr@dumpl ~]$ sudo zfs send -vI @frag7 dpool/f7dump@frag8 >
/dp/nosnap/frag-stream-8-redo4
[sr@dumpl ~]$ sudo zfs promote dpool/dump
[sr@dumpl ~]$ sudo zfs clone dpool/dump@frag7 dpool/frag-tgt-redo4
[sr@dumpl ~]$ sudo zfs promote dpool/frag-tgt-redo4
[sr@dumpl ~]$ sudo zfs receive -Fv dpool/frag-tgt-redo4 <
/dp/nosnap/frag-stream-8-redo4
[sr@dumpl ~]$ sudo zfs promote dpool/dump
```
After receiving I check the file like this:
```
[sr@dumpl temp]$ pushd /dpool/dump/frag-tgt-redo2/.zfs/snapshot/frag8
[sr@dumpl frag8]$ md5sum backup/macbook/gila/Library/Application\
