           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal

I tried clang r200862 and 3.3 release and they both miscompile vlc. One of vlcs
build utilities crashes during the build:

make[4]: Entering directory
`/usr/home/rdivacky/vlc-workdir/usr/ports/multimedia/vlc/work/vlc-2.1.2/bin'
  GEN      ../modules/plugins.dat
gmake[4]: *** [../modules/plugins.dat] Segmentation fault (core dumped)

the vlc used is 2.1.2 from
http://download.videolan.org/pub/videolan/vlc/2.1.2/vlc-2.1.2.tar.xz, this is
the configuration used:
