subject: mysqld 10.0.15 segfaults on FreeBSD i386 clang 3.4

>Description:
When MariaDB is built with clang 3.4 on FreeBSD i386 (which is
the default compiler) the server will segfault the moment a
client connects to it. Same behaviour is observed with clang
3.5. Built with clang 3.3 on 10.1 runs without segfaults.
Built on FreeBSD 10.0 (which comes with clang 3.3) runs OK.
>How-To-Repeat:
Use FreeBSD 10.1 i386
Use port to build MariaDB 10.0 or 5.5
Connect to server using client

>Fix:
Build with clang 3.3 or build using Pourdiere (uses 10.0 jail)
