A bug in struct module on the 64-bit platform?

I'm guessing that the expected behavior is
    >>> struct.calcsize('idi')
    20
because the double should be aligned to an 8-byte boundary.
This is the case on my linux/x86_64 machine:
    $ python -c 'import struct; print struct.calcsize("idi")'
    20
I don't know much about 'itanium', but i'd be surprised if they
chose 4-byte alignment for doubles.
