When a task is deleted, the RTEMS task variable code calls a
user provided destructor on the variable.  The code in telnetd
was not updated after it was changed (if I remember correctly)
from a * to a ** passed in.  I think that's what he is referring
to.

Fernando.. have you moved?  I didn't remember you being in
France.
