Bug#815915: initramfs-tools-core: lsinitramfs causes zcat crash when Intel microcode is included in initrd

[Ron Murray <rjmx@rjmx.net>]

Package: initramfs-tools-core
Version: 0.123
Severity: normal

Dear Maintainer,

When using lsinitramfs to check the contents of an initrd:

> root:~# lsinitramfs /boot/initrd.img-4.4.2
> /boot/initrd.img-4.4.2-curly-0
> kernel
> kernel/x86
> kernel/x86/microcode
> kernel/x86/microcode/GenuineIntel.bin
> *** Error in `zcat': double free or corruption (!prev): 0x0000000002236940 ***

lsinitramfs runs fine on my AMD boxes.

It seems that Ubuntu has at least two reports of this: see their bug
numberss 1541076 and 1507443. I don't see a Debian bug report on it, though.
