  I noticed this on my PC164 recently (two to three weeks ago, mabye).

  My first thought was that it was something with the old version of
NetBSD I was running, or maybe how long my system had been up:

alpha$ uname -v
NetBSD 1.5.3_ALPHA (PC164) #0: Mon Feb 11 01:25:05 MST 2002
mhitch@alpha.msu.montana.edu:/usr/cvsroot/src/sys/arch/alpha/compile/PC164

alpha$ uptime
 9:05AM  up 521 days, 21:30, 13 users, load averages: 1.15, 1.14, 1.09

  The duplication of the path seems to eventually go away after some time.

  In my case, pwd usually shows the correct path, but getcwd(3) returns
the bad path:

alpha$ cd /usr/xsrc/xfree/xc/programs/Xserver
alpha$ pwd
/usr/xsrc/xfree/xc/programs/Xserver
alpha$ /tmp/getcwd
cwd = /usr/xsrcxsrc/xfreexfree/xcxc/programsprograms/XserverXserver
alpha$ pwd
/usr/xsrc/xfree/xc/programs/Xserver
alpha$ cd /usr/xsrc/xfree/xc/programs/Xserver/hw/netbsd/amiga
alpha$ pwd
/usr/xsrc/xfree/xc/programs/Xserver/hw/netbsd/amiga
alpha$ /tmp/getcwd
cwd = /usr/xsrcxsrc/xfreexfree/xcxc/programsprograms/XserverXserver/hwhw/netbsdnetbsd/amigaamiga

  I looked through the kernel code and noticed that the directory names
can come from cache, so I was thinking something was going on with the
cached data.  I haven't proceeded any further yet.  I was thinking of
writing a kernel groveler to try to dump out the cached directory names to
see if the cache data was somehow corrupted, but I haven't had time to do
that yet.
