It isn't, the problem shows up on my i386 desktop in grub-emu. On i386 at least,
it shows up with a clean source + patch from my last email:

grub> cmp /grub2-20051007.tar /grub2-20051007.tar.gz
Compare `/grub2-20051007.tar' and `/grub2-20051007.tar.gz':
Differ at the offset 65536: 0x63 [/grub2-20051007.tar], 0x0 
[/grub2-20051007.tar.gz]

I've tried with all these compilers:

I have double checked that the files are identical after decompression, and
the cmp command works correctly with uncompressed files.

The SHA1 hashes of the test data are:
2ca1f322c8d030bbe661de37eddfbe846c9b935e  /mnt/grub2-20051007.tar
fde79ad954b655bbde711684b3a403919928fbb3  /mnt/grub2-20051007.tar.gz

And it is still at:
