Hi,
Yes, I'm seeing that also. I guess version 4.5.2 of the compiler
just isn't as efficient as the most-recent GCC. I edited
include/grub/offsets.h:
And changed:
#define GRUB_KERNEL_I386_PC_NO_REED_SOLOMON_PART 0x7e0
To:
#define GRUB_KERNEL_I386_PC_NO_REED_SOLOMON_PART 0x7f0
And that was enough. phcoder posted to this list not-too-long-ago
with that suggestion for another person as well. He said you can
increase it as long as you don't do it too much and as long as the
value is divisible by 8.

Hello,
having trouble building the latest bzr 3757. This happens with gcc
4.5.2 on Salix/Slackware 13.37 x86_64 system, but doesn't happen with
gcc 4.6.2 on Arch Linux x86_64.
I also checked recent other reports of such problems, but wasn't able
to find a solution.
Here's some output:
