(go ahead and apply that patch, I'll get things fixed as soon as I can.)
If I run a very short tcl program, ala:
set a(b) whee puts -
I get a crash in parrot, ala:

The crash is fragile - doesn't happen if you change the puts to "puts {}", or delete the second line entirely.
I'll try to find a smaller test case.
