[clamav-users] Clamd Segmentation Fault when built on Mac OS X Yosemite

[Al Varnell]

I received a report from a ClamXav user today who attempted to install engine 0.98.7 is having the same issues with clamd segmentation fault 11 and Yosemite 10.10.  

Although there were scattered reports of this same error early on with ClamXav Sentry use with the 0.98.6 engine, the developer was able to work through that one.  The build info on that are as follows:

This happens with both 0.98.6 and 0.98.7 when built on Yosemite (my version of 0.98.6 built on 10.9 ran fine on 10.10). But I just upgraded my server from 10.9 to 10.10 and with today's relase of 0.98.7, this was my first time attempting to build ClamAV under Yosemite.

This article (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63610) seems to describe the issue but a lot of it is beyond me. I've attempted defining MACOSX_DEPLOYMENT_TARGET=10.9 as described in that article but that didn't make a difference (nor am I seeing anything else defining it to 10.10 so I didn't expect it make a difference).
