But you didn't actually do that.

And now you've reassigned this back to initramfs-tools with no
explanation.

It doesn't matter what the input is, if it can trigger a double-free
then that's a bug - in zutils.

Ben.

when installing zutils 1.7-2, /bin/zcat remains untouched. can you
please elaborate why you think i "didn't actually do that"?

Sorry, I looked at the file list on packages.debian.org which turns out
to be stale even though it's showing the current version number.

It didn't show up on this bug's message log because you didn't write
the control commands properly.

So, you conveyed the upstream author's explanation, but it doesn't
answer why it's OK to install that version of zcat as a replacement for
GNU zcat.  I'm sure some people like to have all the cat options when
using zcat interactively, but it is also used programmatically and
probably not only by initramfs-tools.  You seem to have accepted that
and fixed it, so I don't know why you then assigned the bug back.

The double-free bug in zutils zcat is presumably still unfixed, so I'm
cloning a separate bug for that.

I'm leaving #903931 assigned to initramfs-tools since I might as well
work around the zcat incompatibility.  But please don't take it as a
cue to revert the change in zutils, when that is closed.

Ben.
