> We get a segfault when making a call to pd.read_parquet after having made a
> connection to clickhouse via odbc. Like so,
> {code:python}
> import pyodbc
> import pandas as pd
> con_str =
> f"Driver=libclickhouseodbc.so;url=http://clickhouse/query;timeout=600";
> with pyodbc.connect(con_str, autocommit=True) as con:
> pass
> df = pd.DataFrame({'A': [1,1,1], 'B': ['a', 'b', 'c']})
> df.to_parquet('/tmp/foo.pq')
> # This line core dumps:
> pd.read_parquet('/tmp/foo.pq')
> {code}
> This happens with pandas version 1.0.1 but not with pandas 0.25.3. Here's a
