I've done some more testing and have been reliably able to reproduce the
problem. The problem always occurs (in my test setup) when I have
av_scanner set up to a clamd TCP socket, regardless whether it's local
(127.0.01), remote, IPv4 or IPv6, they all SIGSEGV.
When I switch to a local clamd.sock, the problem vanishes.
I'd be curious to know if other people experiencing this problem have a
similar av_scanner setup.
