fix segfault at startup

The previous changes to move the startup TCL code resulted in segfaults
during startup.  This seemingly innocuous patch fixes the problem.
I would explain why changing from 'foo[]' to '*foo' caused this issue,
but the difference seems superficial.  For now, this hot fix will do,
but this issue might bear further scrutiny.
