This is also an issue without sudo on user files:

clamdscan --multiscan --quiet --fdpass --move=Downloads/Quarantine --log=Downloads/ClamavScanSchedule.log ~/Desktop/
Segmentation fault: 11

[jmroot (Joshua Root)]

Please attach the crash log.

[essandess (Steve Smith)]

Passing the flag --fdpass causes the issue.

Here's What I see from a core dump:

Enable core dumps:

ulimit -c unlimited
sudo launchctl limit core unlimited

Dump core:

sudo clamdscan --multiscan --quiet --fdpass --move=/opt/Quarantine/ --log=/opt/local/var/log/clamav/ClamavScanSchedule.log 
Segmentation fault: 11

Disable core dumps:

ulimit -c 0
sudo launchctl limit core 0 unlimited

So, first can you upgrade to 0.103.2 and see if that bug is still present? If it is, can you report it upstream and then include the link to your report here? At first look, it doesn't appear to be related to the port - I'm happy to update MacPorts once upstream fixes it, though.

[essandess (Steve Smith)]

I'm at:

$ clamdscan --version
ClamAV 0.103.2/26102/Mon Mar  8 07:03:13 2021

But this appears to be known and fixed: ​https://bugzilla.clamav.net/show_bug.cgi?id=12676

I'll try the most recent release and issue a PR.

Also, livecheck isn't working for this port. I'm not a livecheck expert, so I may defer this to the maintainer.

$ port livecheck clamav
Error: cannot check if clamav was updated (The requested URL returned error: 403 Forbidden)

[essandess (Steve Smith)]

Nope, ClamAV 0.103.2 is the latest release, so this remains an active issue, at least on macOS. I've submitted a bug report:

​https://bugzilla.clamav.net/show_bug.cgi?id=12727

[danielluke (Daniel J. Luke)]

From the first bug report you linked, looks like it will be fixed in 0.104. We can update the port with a patch (although it looks like they made some additional related changes in the 0.104 branch) or wait for the 0.104 release.

The livecheck works for me (it's just pulling ​http://www.clamav.net/downloads and using a regex to look for version numbers).
