Straight segmentation fault when using psi4 (even just psi4 --version)

build
3

Could you try to comment out the v2rdm_casscf plugin in this file:

<conda_path>/envs/<psi4_env_name>//lib/python3.7/site-packages/psi4/driver/endorsed_plugins.py

(or find <conda_installation_path> -name endorsed_plugins.py)

This section:

try:
    import v2rdm_casscf
except ImportError:
    pass

I know the plugin causes segmentation fault on some of my machines.
