Hello,
I have some more information about this issue, another person running
Ubuntu 20.04.3 LTS was able to reproduce the same issue (using WSL). Also,
I tried to debug the issue in GDB, and this seems to be the origin of the
segmentation fault. Is there anything else I can help with to get closer to
the source of the problem?
