Follow-up Comment #2, bug #57741 (project gforth):

[comment #1 comment #1:]
> We could fix this by adding a memory access in DROP (and some other words),
but I am not sure if this is worth the effort and the slowdown.

With the debugging engine (gforth), it's probably worth it.  We don't do TOS
caching there only to get precise stack empty traps, and it hurts performance
more than an unused read in DROP.
