[clamav-users] Clamscan crash on Mac OS X - yara rules

You almost certainly need to attach it to a ticket at <https://bugzilla.clamav.net <https://bugzilla.clamav.net/>>. I don't see how anybody would be able to make sense of a partial crash report.

That being said, it's almost certainly the result of a misconfigured yara rule, so they will need to see that, as well, if you have the time to narrow it down to a single list. I know there is already an open ticket on a previous rule from an UNOFFICIAL definition list.
