[Bug 1507002] Re: "boot error" due to gcc v5 transition

[sudodus]

A new version of the Ubuntu Startup Disk Creator is released in the
developing version of Ubuntu, Xenial Xerus.

That version is neither affected by this bug, nor by other old bugs, and
the intention is to do some basic debugging and testing, and after that
I hope it can be back-ported into previous versions of Ubuntu and the
Ubuntu flavours (Kubuntu, Lubuntu ... Xubuntu).

Until then you can use some other tool to create USB boot drives, for
example mkusb, which 'wraps a safety belt around dd',

Title:
  "boot error" due to gcc v5 transition

Status in syslinux package in Ubuntu:
  Triaged

Bug description:
  Today I upgraded to Ubuntu 15.10 (wily) from vivid and creating boot
  disks (USB, vfat) stopped working.

  I tried my best to find what's the problem, but I couldn't identify
  it. It looks like it's related to LP: #398241 (or the debian bug
  referred there)

  Essentially, I did

  1. create empty USB disk
  2. format as vfat (mkfs -t ... -- -F32 -n 'label')
  3. syslinux --install path/to/image -t 512
  4. boot a computer with it
  5. SYSLINUX 6.03 ... "boot error" <-- is displayed

  I then downgraded to syslinux 3:6.03+dfsg-5ubuntu1, did the same
  thing, and it worked again.

  I believe this is related to ldlinux.sys, ldlinux.c32, linux.c32,
  menu.c32,  or libutil.c32, since at least the machine boots to
  syslinux, it simply does not proceed to display my menu.
