Description
When connecting to a CAS server with a username and password, it is possible to hit a segmentation fault if the credentials are incorrect! This totally exits out of the Python program/shell. Below is an example program that I can reproduce this with. Obviously, I have removed the machine, username, and password for privacy reasons:
from swat import *
s = CAS('<machine_ip_address_or_hostname>', 5570, '<username>', '<password>')
The result of running this is Segmentation Fault (core dumped) if the credentials are incorrect.

Research direction
Start with the provided Python example and the CAS constructor, reproducing the failure with incorrect credentials. Trace the connection and authentication handling to determine where the segmentation fault occurs; done means invalid credentials return a handled error instead of terminating the Python process.
