segfault using console-solver when checked out from source

[ghost]

If I build from source on linux I keep getting a segfault when testing the console-solver, here is the backtrace, it seems to work fine when single threaded, but 2 threads or more and it crashes, also the precompiled download works fine with 8 threads.

#run with 2 threads

The problem is most likely related with OPENMP. In the readme file I provided a sample google colab to show how to compile from scratch

https://colab.research.google.com/drive/1NWDb53ypcKpkb3g3orzEBDeHAEkAIC7y

I suggest that:

• check the version of your cmake, openmp,etc
• check the colab file to find out exactly where is different between our compile process, I use that colab file to get the Linux release, so it works 100%
• if both doesn't work, paste your full compile log

Discovered my error - when using it from the install directory it works fine, I was mistakenly using it from the build directory. Sorry for the error.
