unaligned access: a request

[Angus Leeming <a.leeming@ic.ac.uk>]

José, (or indeed anyone else reading this list)

I have a request to make.

Attached is a stripped down version of the code in
xtl-1.3/examples/tests

You'll see that the only test I do is on class numbers and
the only data member of numbers is a bool.

I've compiled this code on a LinuxAlpha machine without
problems.
All three tests, raw, xdr and giop pass.
All three tests produce the same error messages in
/var/log/kern.log:

You'll note that the addresses are identical in all three
cases.

My request is this:
Could you run the test on an x86 machine and then look to
see if there are any error messages in /var/log/kern.log.
I'm interested to see whether this is an Alpha-specific
problem.

Regards,
Angus
