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

The problem would come up after I would burn a 32 bit iso  using Startup
Disk Creator.
The usb stick with the 32 bit iso would never boot into the state where I
could "Try Ubuntu".
With dd the problem was solved. I could "Try Ubuntu" and/or "Install
Ubuntu".
Is there perhaps a way to compare 2 usb sticks, byte by byte, to see the
difference between the output of Startup Disk Creator and dd?
(Use a 32 bit iso.)

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.
