[clamav-users] ExcludePath Segmentation Fault Errorr

[Micah Snyder (micasnyd)]

Hi Michael,

It looks to me like you've stumbled across this issue: https://bugzilla.clamav.net/show_bug.cgi?id=12676

I have a fix on the way.  The attached patch works, though I am still tidying up some additional error handling cleanup work per peer review. 

Regards,
Micah
