Note that the second run produces different results. In fact each run
produces different results. (the length of the garbage sometimes
differs, too).

I played arround following your route above (hacked your script to
doing
echo "processed $file:"
sed 's,\x1f,X,g' < "$ODIR/dir"|file -
after each processed file)
...
processed /usr/share/info/screen.info.gz:
/dev/stdin: UTF-8 Unicode English text
processed /usr/share/info/maplev.gz:
/dev/stdin: data
...
=> probably maplev is the bad one.
karme@kallisto:/tmp$ dlocate /usr/share/info/maplev.gz
emacs-goodies-el: /usr/share/info/maplev.gz
karme@kallisto:/tmp$ debsums -s emacs-goodies-el
karme@kallisto:/tmp$ md5sum /usr/share/info/maplev.gz
98717e7b29692eb90ed810dfc26407d3 /usr/share/info/maplev.gz
Some further tests ...
For me this looks like some memory corruption in ginstall-info. I can
only successfully reproduce it using a quite filled dir as base. Running
ginstall-info under valgrind the output file looks ok.
Attached a base dir file
(dir.ok, md5: e72d028e3fa665a9368b88b07f094864)
I then do:
$ cp dir.ok dir
$ ginstall-info /usr/share/info/maplev.gz dir
now the dir file broken.
Greetings
