Re: ClamAV 0.102.3 - Can't allocate memory ERROR on macOS 10.15

I just tried reproducing the issue using 0.102.3, both with the file you provided and with my own copy (it turns out I have that filepath on my mac already).  Wasn’t able to reproduce the error with clamscan, clamdscan, or clamdscan –fdpass.  Not sure how to help.

Anyone else have any ideas?

Hi Micah,

Thanks. I've uploaded it to clamav.net <http://clamav.net/> as an FP report.

Here are the various hashes to help you find it.
