the above means the tcl is trying to delete a hash table entry that is not there
anymore for some reason

you've probably got a malloc arena corruption or double free of some kind happening
if i had to make a  off the cuff guess. it you have C extensions
that would be the first place to look. but it could just be a subtle
7x threading bug.. in which case. you'd have to break out purify or electric fence

i know of people having this problem in tcl7.6 when using the rename command
under certain situations.
