Hello.

On fresh installed system - 

10.0-CURRENT FreeBSD 10.0-CURRENT #3 r255173: Tue Sep  3 13:31:22 EEST 2013

With fresh i386 builded jail. I'm found some bug with core dumped uniq (/usr/bin/uniq)

After recompile whole system with debug symbols found some trace 

gdb /usr/bin/uniq uniq-1676.core

I's any change to fix problem ?
