Hello Michael Chan, Thank you for the bug report. I tried to reproduce your issue using MySQL ODBC 8.0 Unicode Driver with Python 3.9, pyodbc 4.0.32 and pyarrow 6.0.1 but I am not seeing any issues at my end. Regards, Ashwini Patil

Description: In python, when using pyodbc with MySQL ODBC 8.0 Unicode Driver, it crashes with seg fault when the pyarrow module has been imported in the python program Remarks: MySQL ODBC 5.3 Unicode Driver does not have the problem. This problem only occurs in MySQL ODBC 8.0 Unicode Driver Python package versions: pyarrow 4.0.1 pypi_0 pypi pyodbc 4.0.27 py36he6710b0_0 defaults python 3.6.12 hcff3b4d_2 defaults MYSQL versions: mysql-connector-odbc.x86_64 8.0.25-1.el7 @mysql-connectors-community Crash Stack Trace: (gdb) where #0 0x000000000006b946 in ??
