[Bug 837815] Re: Grub 0.97-29ubuntu62 gives error "Error 6: Mismatched or corrupt version of stage1/stage2"

[Colin Watson]

I think this is down to GCC 4.5 vs. 4.6; compiling with gcc-4.5 seems to
avoid this.  From the GCC 4.6 release notes:

  * A new inter-procedural static profile estimation pass detects
functions that are executed once or unlikely to be executed. Unlikely
executed functions are optimized for size. Functions executed once are
optimized for size except for the inner loops.

  * On most targets with named section support, functions used only at
startup (static constructors and main), functions used only at exit and
functions detected to be cold are placed into separate text segment
subsections. This extends the -freorder-functions feature and is
controlled by the same switch. The goal is to improve the startup time
of large C++ programs.

    Proper function placement requires linker support. GNU ld 2.21.51 on
ELF targets was updated to place those functions together within the
text section leading to better code locality and faster startup times of
large C++ programs. The feature is also supported in the Apple linker.
Support in the gold linker is planned.

Using -fno-reorder-functions also appears to avoid the problem, so I
suspect that will be the answer.

Bug description:
  On the Oneiric testing system, I ran grub-install to reinstall grub
  for Debian Lenny.

  $ cat /etc/lsb-release
  DISTRIB_ID=Ubuntu
  DISTRIB_RELEASE=11.10
  DISTRIB_CODENAME=oneiric
  DISTRIB_DESCRIPTION="Ubuntu oneiric (development branch)"

  The version of grub:
  $  dpkg -l |grep grub
  ii  grub                            0.97-29ubuntu62                         GRand Unified Bootloader (Legacy version)
  ii  grub-common                     1.99-11ubuntu1                          GRand Unified Bootloader (common files)

  
  Debian Lenny is on /dev/sda:
  $ parted -s /dev/sda print
  Model: ATA VMware Virtual I (scsi)
  Disk /dev/sda: 17.2GB
  Sector size (logical/physical): 512B/512B

  The root partition of Debian Lenny is /dev/sda1, therefore:
  1. mount /dev/sda1 /mnt/
  2. ls -alFd /mnt/boot/grub/

  After downgrading to the grub version on Natty, i.e. grub_0.97-29ubuntu61, it works:
  $ dpkg -i grub_0.97-29ubuntu61_i386.deb
