Extended Description

Created an attachment (id=688)
source code to reproduce fault
In the ongoing battle to kill CYC, we need to extend LS to make it
support SAA. When it moves a value from within a LACFUN to outside it, 
it fails to move the AVIS_SHAPE/DIM information for that. 
This results in unpleasant failure modes, such as VPid dying.
The attached will fail if compiled with rbe's local sac2c
(the post-Loch Ness fixerupper that is not checked in yet), with these options:
sac2c -ecc -extrema -doawlf -nowlf ipbbAKD.sac
This is partly a place marker so that we remember to do this work.
