This provides a better experience than just marking them as

COI model converter has to use constraints from the body and work in disjunctive mode. It needs a pre-condition that the body does not depend on other rules, in the case that it is used in a different pre-processing step for in-lining. The in-lined occurrence of the predicate has to correspond to the model construction version.

Nikolaj Bjorner fc77345bec breaking change. Enforce append semantics everywhere for parameter updates #5744 
Replace semantics doesn't work with assumptions made elsewhere in code.
The remedy is to apply append (override) semantics for parameter changes.

Nikolaj Bjorner a099972354 fix #5714 
It is not unlike other fuzz bugs: it exercises some behavior that applications are unlikely to expose. In this case, a rule body expanded into a conjunction with more than 1M formulas (with a lot of repetition). The original rule representation assumed silently that the number of constraints in a body would fit within 20 bits, but reality allowed bodies with as many as 2^{32} - 1 constraints.
So "minimizing" the bug as @agurfinkel asks for seems not to make too much sense.

Just running the samples in debug mode  points to the root cause.

Since fuzz bugs are not from applications and fuzz tools have the potential for creating a large number of issues, I find it reasonable to push some basic pro-active asks on filers:

- reproduce bug in debug builds to assess whether a debug assert triggers.
- minimize or keep it simpler when possible (in this case it does not apply)
- perform basic diagnostics/triage. I am basically asking to push this part of the work on to the fuzzer. Otherwise, addressing random bugs doesn't scale. Triaging should have pointed to the root cause.

Now, there tends to be something to learn from bugs. In this case, the question was: "can we avoid constraints with duplications"? In particular, it points to a basic inefficiency of extracting conjunctions (and disjunctions). The function didn't deduplicate. So I added deduplication into this function. It is used throughout z3 code base so could expose latent issues. We will see.
