I guess you refer to this issue
https://github.com/backuppc/rsync-bpc/issues/28?

Correct.

I'll see if I can try downgrading rsync-bpc to v3.1.2.2.

I'd very much like to know if that fixes your problem.

Do you have a Github repo with this 3.4.1rc1 version?

No.  Github gives me terrible trouble at the best of times and I'm
reluctant to push anything until it's had more testing anyway.

Is there a reason you don't want to work from a tarball?  A .zip file
from Github is more or less the same thing with different compression.

The memory and swap usage of this BackupPC server is already monitored, and
I've not seen a spike in memory or swap usage during the night. And I see
no OOM messages in dmesg or kern.log neither.

Maybe there's something else going on.  Do you know for sure that the
segfault is caused by rsync-bpc, and not for example by BackupPC-XS?

...
These garbled lines seems to be detected as errors and shown when one
clicks on the "Errors" links in the "Xfer Error Summary" as they do not
match the usual same/new/pool/del keyword lines?

Interesting, and thank you!  I hadn't spotted that, I'll look into it.

After re-reading the documentation ... I've kept the "rsync" method ...

For more than one reason I think that's best.
