I have been getting this error on OS X 10.3.2 ("gcc (GCC) 3.3 20030304 
(Apple Computer, Inc. build 1495)") but with no core dump regardless if 
I run test_tcl directly or by execing ``regrtest.py -unetwork`` (how I 
always run the test suite).  I do have Tcl installed on my system and 
you can import Tkinter but I get the usual "SetFrontProcess failed,-606" 
error that you get on OS X unless you use the pythonw executable with Tk 
code.
