Hi, there.
There is a use after free issue that causes segmentation fault using z3.
It might also become exploitable since it can modify the memory space.
To reproduce this issue, simply run

Z3 crashes with a segmentation fault, and I was able to get this backtrace:

If STP is submitted practically unchanged, perhaps with a novel SAT solver, to SMTCOMP. Does anyone think we should ask for anything, or be involved in some way, beyond just an acknowledgement in the …

Hi,
The smt2 files and cvc files generated by KLEE have different solving results.
For example, in the attachment, the result of ```stp klee-last/test000002.smt2``` is "sat" and the result of ```s…

Hi,
For this formula,
```
(set-logic NRA)
(declare-fun a () Real)
(assert (>= a 6.0))
(assert (>= (/ 1.0 (+ a 1.0)) 0))
(check-sat)
(get-model)
```
CVC4 reports unknown but produces a model…

Consider the below trace which shows a soundness bug on a NRA formula. Z3 (master + debug) return `sat`, CVC4 gives `unsat` on bug.smt2. Feeding Z3's model to the formula yields `unsat`.
