I wouldn't be surprised, but I don't understand the problem.

These are what I would expect on a 32 or 64 bit platform. i == int, d
== float. ints are typically 4 bytes on 64 bit platforms. If you want
8 byte integers, you typically need to use longs (format letter is ell,
l).
You didn't say which version of python, so it's possible this was a bug
that was fixed too.
On my system:
python: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for
GNU/Linux 2.4.1, dynamically linked (uses shared libs), not stripped
>>> struct.calcsize('l') #that's a lowercase ell
8
If you think it's a bug, you should file a bug report on source forge.
