The traceback shows that it crashes where tkined receives data from
the discover process. However, there is not enough information in the
traceback to see what is going on. What is needed is either a simple
example that reproduces the problem or more debugging information.
Setting tki_Debug to 1 somewhere in the C source will print a trace of
the messages exchanged between the discover script and tkined. Also,
compiling tkined with -g allows to find out which call to
Tcl_DStringFree() in receive() failed and what the data structures
(objecty->done and objecty->cmd) looked like when it crashed.
