Hi there!
I don't know if the following information will help or will create more
confusion.

I'm using XOTcl 1.5.3 compiled from scratch against Tcl 8.4.5.
I've been able to reproduce the bug using the tcl shell installed on my
system (info patchlevel ==>8.4.9).

Surprisingly, everything works fine if I source your scripts in the Tcl
shell embedded in the commercial software I'm working with (info
patchlevel ==> 8.4.5.1).

II'm at your disposal for providing you any additional info you might
find interesting if you believe this could give hints for debugging,

Regards,
Nico
