That's what I thought. :)

As it happens  it is still running...

(gdb) up

How would I go about checking this?  
I have ran 'make uninstall' from both fr3.0.0 and fr3.0.1 source directories; then ran make install again from 3.0.1 but I still get a segfault.
To confirm, if I then re-install fr3.0.0 it runs.

Many thanks,
Jezz.
