clearing oct files

Hi,

I've just started playing with integrating some C/C++ tools with octave
using oct files. I was wondering if it's possible to have octave pick up a
recompiled .oct file without restarting octave. I've seen different
behavior when trying to do this including a crash like the one in the
closed bug report here:

http://savannah.gnu.org/bugs/?34861

Eg:
warning: library /tmp/foo.oct not reloaded due to existing references
fatal: caught signal Segmentation fault -- stopping myself...
Segmentation fault (core dumped)

If I remove the .oct file and call it, it says it's undefined and doesn't
crash. If I then copy the new one, it doesn't crash, but it also doesn't
pick up the changes until I exit octave and restart. Is that old bug really
fixed? I'm using 6.2.0.

Thanks,

        David

On a related topic, if the .oct file is a symbolic link and you clear the
function, it behaves just as if the .oct file didn't change when the
destination of the symlink changes.
