OOM during cargo mirai project analysis

[Andrey Fedotov]

Issue

Hi! 👋
I'm looking a SAST tool for our Rust project CASR and found your interesting project!
But, unfortunately I failed to analyze libcasr due to oom. It's seems to me that I need somehow to set limits to Z3.
Could you help me please not to OOM?

Steps to Reproduce

git clone https://github.com/ispras/casr.git
cd casr/libcasr
cargo mirai

Expected Behavior

Analysis correctly finished.

Actual Results

Checking libcasr v2.8.1 (/home/fedotoff/casr/libcasr)
error: could not compile `libcasr` (lib)
