BSOD in aswSnx.sys

I started having these BSODs when compiling software, extremely reproduceable (practically reproduceable every time in the middle of the work), I’ve uploaded 2 minidumps to the incoming folder of the ftp (those starting with BSOD_aswsnx_sys_win7x64). I’ve tried both 1125 and current pre-release 1198, but that made no difference.
I had to uninstall Avast, otherwise I couldn’t work. After the uninstall no more BSODs.
Thanks, I hope to be able to reinstall a new version soon.
