I've seen that others have responded too, and indeed it's just the sizebyte
that gets overwitten with a wrong value. But why are u, v and w most
common to have this (from what I've seen)? Are they created before any
other vars? So the stack could overwrite their VAT info, and buggy asm
programs their sizebytes?

I do know that there are variables (like the 'Yn=') that shouldn't be
deleted as since the TIOS expects that they always exist. When you deleted
them via the TIOS (mem -> delete -> all) they are merely resized to 0
bytes. See the Ti83+ sdk for more info.
