Known issues as of 3.0RC1.
The CUDA pattern scanning support is broken in 3.0. It may get fixed later in the 3.0 series.
A known broken PCRE version based on libpcre 8.35 contains a stack corruption bug. This leads to risk of crashes with certain rules + certain traffic. https://redmine.openinfosecfoundation.org/issues/1693
Recommended solution is to install your own libpcre version for those distros that have only version 8.35
- Debian Jessie - It has been reported to Debian Security but isn't fixed yet.
- Ubuntu Willy 15.10
- Gentoo (LiveCD) (as of Feb 2016)
