I meet an error when I run CP-SAT python program.

It shows

WARNING: Logging before InitGoogleLogging() is written to STDERR

F0514 14:49:35.268787 32288 cp_model_presolve.cc:91] Check failed: !DomainIsEmpty(ref)

*** Check failure stack trace: ***

How can I check where does the error come from?

Because I meet an int_max overflow error in ortools 7.1 as mentioned in this post https://groups.google.com/forum/#!topic/or-tools-discuss/RBol-pOiJo0 , I roll back to 7.0 now.

I meet F0514 in some dataset of ortools 7.0, but my program in other dataset works well and without warning.

Fixed 7.1 have been pushed for windows.
