Z3 Quantifier Elimination Crashes #263

Closed lembergerth closed 2 years ago

lembergerth commented 2 years ago

Running this code in CPAchecker, which uses java-smt, crashes:

// QuantifiedFormulaManagerView qfmgr;
BooleanFormula quantifiedFormula = qfmgr.exists(a2, formula);

eliminationResult = qfmgr.eliminateQuantifiers(quantifiedFormula);

with a2 == "|main::a@2|" and this formula:

(and (= |main::a@2| #x00000006)
     (= |main::b@2| #x00000006)
     (= |main::a@3| #x00000000))

The issue seems to be in

I'm not sure how to debug further. Maybe someone can give some pointers?

If you want to reproduce in CPAchecker, I've used the following command line:

scripts/cpa.sh  -predicateAnalysis \
   -setprop cpa.predicate.abstraction.computation=ELIMINATION \
   -setprop solver.solver=Z3 \
   -setprop analysis.algorithm.CEGAR=false \
   loop-simple/nested_2.c

and loop-simple/nested_2.c is this program:

My approach would be trying to recreate the problem in a JavaSMT program, recreate that using only native Z3 and then either find out why it fails in one and not the other, or ask the Z3 devs. If you want to i can do that over the weekend.

baierd commented 2 years ago

This seems to be caused by our API usage. I can confirm that this crash is happening with JavaSMT API, but it does not happen using native Z3 Java API.

baierd commented 2 years ago

I have further investigated this. There are 2 kinds of Java APIs usable, the default front end that is properly documented and the direct JNI bindings (which we use in JavaSMT). Using the direct JNI bindings i can confirm that this crash persists. The problem seems to the the applyResultDecRef() cleaning up intermediate results of the quantifier elimination in the Z3FormulaCreator line 825. However, since every decRef call also seems to need a incRef call i don't really understand why it is there in the first place as the results are never incRefd. We could simply remove the applyResultDecRef() call in the tactics. This would, in the worst case, result in leaking some memory for multiple tactic applications, which does not happen often. @kfriedberger what do you think? You have more information regarding the Z3 implementation than i do.

lembergerth commented 2 years ago

Thanks for looking into it so well! :-) Please tell me if I can help in any way.

kfriedberger commented 2 years ago

I will take a look. If an intermediate result is still referenced internally in Z3, we should not recrement the reference-counter. In worst case, this might result in a small memory-leak.

If this can be fixed easily (seems so), than we can backport this fix in JavaSMT especally for usage in CPAchecker, because the tool still depends on an older version of JavaSMT (dependency issue with SMTInterpol and LassoRanker, referenced in CPAchecker issue-tracker).

kfriedberger commented 2 years ago

@lembergerth I have commited JavaSMT in an intermediate version 3.11.0-129-g398a4a02 into the Ivy repository. I assume you have more tests or benchmarks in CPAchecker for applying quantifier elimination. Could you (locally) patch CPAchecker with the following patch javasmt_3.11.0-129.patch (hopefully sufficient) to update the version of JavaSMT, and then test whether this issue is fixed (and no other problem was introduced)?

Then we can think about how to properly update JavaSMT in CPAchecker.

lembergerth commented 2 years ago

Thanks! The patch seems to work well. Initially I only had a few small examples, so I also ran integration-predicate-bitprecise.xml with these adjustments:

Results look good with regards to the solver; only a single crash. I think it's unrelated to this issue, but for completeness:

I could not reproduce the segfault reported in the last comment. Can you tell me whether you need an updated version of JavaSMT for CPAchecker? In that case, we need to backport some bugfixes and deploy an intermediate branching version, because we can not update SMTInterpol in CPAchecker, and the newest JavaSMT would bring a new SMTInterpol.

Me neither. It only happened on the verifier cloud.

Can you tell me whether you need an updated version of JavaSMT for CPAchecker?

Depends on what time-frame we are talking about for a proper next version with the fix. It would be great if this could be fixed within the coming months, but it's not urgent for the foreseeable future.
