ExcludeNodes torrc option doesn't work for me

[Thomas Barvo]

I have tried the exclude nodes option in torrc but this does not work
for me. I monitor my IP address when I use tor in real time and the
exit nodes always change to the one(s) excluded in my torrc file at
some point. Is the RendExcludeNodes option also ignored? I have tried
removing contents of my ~/.tor directory and restarting tor, this
attempt fails too, exit nodes I blocked in torrc by nickname or
fingerprint are still used. What am I doing wrong or how do I fix
this? My torrc file is located at /usr/local/etc/tor/torrc, should I
cp it to ~/.tor ? Placement should not matter as other options are
respected, but not ExcludeNodes!
