Z3 API: Crash when parsing fixed point SMTLib string

QUESTION

Z3 API: Crash when parsing fixed point SMTLib string

Asked 2017-Mar-10 at 02:26

I am trying to use the C/C++ API of Z3 to parse fixed point constraints in the SMTLib2 format (specifically files produced by SeaHorn). However, my application crashes when parsing the string (I am using the Z3_fixedpoint_from_string method). The Z3 version I'm working with is version 4.5.1 64 bit.

The SMTLib file I try to parse works find with the Z3 binary, which I have compiled from the sources, but it runs into a segmentation fault when calling Z3_fixedpoint_from_string. I narrowed the problem down to the point that I think the issue is related to adding relations to the fixed point context. A simple example that produces a seg fault on my machine is the following:

The fixedpoint object "f" is reference counted. the caller is responsible for taking a reference count immediately after it is created. It is easier to use C++ smart pointers to control this, similar to how we control it for other objects. The C++ API does not have a wrapper for fixedpoint objects so you would have to create your own in the style of other wrappers.

Instead of del_fixedpoint one uses reference counters.

Install seahorn

The install target installs SeaHorn all of it dependencies under build/run. The main executable is build/run/bin/sea.
cd seahorn ; mkdir build ; cd build (The build directory can also be outside the source directory.)
cmake -DCMAKE_INSTALL_PREFIX=run ../ (Add -GNinja to use the Ninja generator instead of the default one. Build types (Release, Debug) can be set with -DCMAKE_BUILD_TYPE=<TYPE>.)
cmake --build . to build dependencies (Z3 and LLVM)
cmake --build . --target extra && cmake .. to download extra packages
cmake --build . --target crab && cmake .. to configure crab (if extra target was run)
cmake --build . --target install to build seahorn and install everything in run directory
