Hmm, looks like the new test cases have turned up a pre-existing bug.
Some of the buildfarm is showing crashes :-(. It looks like all the
unhappy critters are running Tcl 8.4.something, which might be a
coincidence but I bet not.
I get the impression it's a stack clobber or memory clobber associated
with reporting Tcl errors back to PG, but haven't been able to isolate
it yet.
