Yepp, that's what Tom meant.

Tom, let me add to it that I noticed recently that libpgtcl
isn't Tcl8.3 safe. It didn't went that far for me (no core
dumps), but it mangled some inputs because Tcl8.3 does
anything internally in UNICODE (IIRC) and the libpgtcl
functions don't care for encoding.

For the actual error, I cannot reproduce that with 7.0.3 and
Tcl8.3 here on RedHAT 6.1. So there might be as well
something wrong with his Tcl installation.
