[Magic-dev] Bad error in 7.3 from revision 117 to 121

[R. Timothy Edwards]

I got a report from Eric Wong at U.Md. of a rather bad bug that I
introduced into the code in revision 117.  I was attempting to get
rid of a more subtle bug, the one that caused magic to report
something like "cells are so small that non-neighboring cells may
have interacting CIF!".  But a one point, the CIF/GDS array
interaction generation routine can return while leaving array
bounds messed up, and arrays of cells in the layout can be reduced
to 2 without notice.  If you have magic 7.3.117 to magic 7.3.121,
you should update to 7.3.122 to avoid having any layout auto-revised
in a bad way during a CIF or GDS write.
