Extended Description

Created an attachment (id=983)
source code to reproduce fault
If the attached is compiled this way, it produces incorrect answers:
 sac2c buguip.sac
If compiled this way, it runs correctly:
 sac2c buguip.sac -nouip
I believe the problem is that UIP uses the wrong
criterion to decide whether update-in-place (RC(xxx))
can be used. Compiling with -bopt | grep RC shows
this difference.
The fault is related to multiple partitions in a single WL. 
The criterion used for any partition is this:
  CRIT: X[ iv] = f [ x[iv]];
That is, the modarray does not require access to any element
of X other than X[iv]. 
The criteria for the entire WL is:
  any (CRIT)
but it should be:
  all (CRIT)
