This must be related to system libraries...

address@hidden ~]$ echo /overlay/sys-apps/hwinfo | 
egrep -o '[^/]+/[^/]+$'
sys-apps/hwinfo
address@hidden ~]$ echo $?
0
address@hidden ~]$ egrep --version
GNU grep 2.5.3

This is on Ark Linux (glibc 2.6.1, built with gcc 4.2.1).

What OS/libc does it fail on?
