This is a problem that we also occasionally get -- and fix to the extent 
we know about it.  It happens when the cerl_to_icode translation fails 
for some reason or another.  Typically, this is because the translation 
does not properly handle the new boolean operators ("andalso" and "orelse").

First of all, I suggest you identify the code on which this happens (by 
dialyzing one file at a time, until you get the error).  Please send us 
that code.  If the code contains "andalso" and "orelse" then most 
probably it's due to their presense. If so, you have two options to deal 
with this:

  - Either compile without +debug_option and dialyze that .beam file
  - Change uses of "andalso" to "," and "orelse" to ";".
