Comment (by simonpj):

 I'm a bit lost in all this.  Is there a small reproducible test case I can
 look at?  What exactly is being compared with what?

 I'm also lost with the SAT discussion.  I think SAT is off by default; and
 it usually applies to recursive definitions, which in turn usually do not
 have ININE pragmas.

 Sorry to be dim.  Maybe start from zero and explain one bit at a time?
