Environment

• Python: 3.10.12
• pyodbc: 5.0.0
• sqlalchemy: 2.0.21
• OS: Ubuntu 22.04 64bit
• DB: MSSQL (AzureSQL)
• driver: Microsoft ODBC Driver 18 for SQL Server (/opt/microsoft/msodbcsql18/lib64/libmsodbcsql-18.3.so.2.1)
• login method: token

Issue

Trying to connect with token as described in:
https://docs.sqlalchemy.org/en/20/dialects/mssql.html#connecting-to-databases-with-access-tokens

How to reproduce:

• login with az login on your machine (in MS way)
• copy-paste sample code from the link and fill server/database
• add engine.connect() at the end
• observe segmentation fault (core dumped)

Observations:
pyodbc 4.0.38 is not affected - above samples works well
Just pip install --upgrade pyodbc==4.0.38 solves the issue, in the same environment
Login with user-password works well
