I'm busy with a lot of other things but I am well aware of this issue. You
can silence the noise with "dmesg -n1".

Otherwise, it would be greatly appreciated if you could work on a patch to
fix this issue.

On my alpha, the system logs are getting spammed with unaligned trap
errors as follows:

[34656.586748] dbus-daemon(700): unaligned trap at 00000200000a9720: 00000000d68c7222 28 18
[34656.599443] dbus-daemon(700): unaligned trap at 00000200000a9720: 00000000d68c7222 28 18

[34656.617021] dbus-daemon(700): unaligned trap at 00000200000a9720: 00000000d68c7222 28 18

The current "dbus" package version is 1.12.16-2.

If no one else is actively working to fix this annoyance, I'll see what
I can do. For me, it's mostly a matter of finding the time to download
the source package and its dependencies, build a debug version with
symbols in it that "gdb" can use, and then *maybe* figure out the best
way to code around the unaligned access.

If anyone else has the time and would like to have a go at it, the
following two links might be useful:

https://wiki.gentoo.org/wiki/Project:Alpha/Porting_guide#Unaligned_accesses

https://www.redhat.com/archives/axp-list/2000-May/msg00151.html

(Yes, the problem has been around at least as long as the alpha
architecture :-) ).

Michael Cree et al.: do we have a working "gdb" on alpha these days?
I seem to recall brokenness there in the not-too-distant past.

At first glance, that certainly appears to be the issue. The
conversation seems to have stalled-out as of July 2019.

memcpy() looks to be a good way of handling the problem, for the
reasons mentioned. Did you try that fix? If so, did it work for you?

Yes, it works.

The suggested one line change did work and fixed the issue for me.

I didn't have time to ask for it to be merged.
