>Description:
Installed from ports clamd uses -lthr for threading.  With this enabled clamd crashes when doing the database checks.  Using all the same arguments to configure but either dropping -lthr or using -lpthread resolves this issue.

Strangely when run in foreground mode clamd does not crash.
>How-To-Repeat:
Install clamav 0.90.1 from ports on 5.4
Set the clamd SelfCheck interval low (say 10 seconds)
Start clamd
Wait until the SelfCheck interval has passed
Use clamdscan (or any other tool that calls clamd) to scan a file or directory
Watch clamd crash silently.
>Fix:
Either remove -lthr or replace with -lpthread
