BUG: read_sas segfault

[wudihero2]

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pandas.

• I have confirmed this bug exists on the master branch of pandas.

Reproducible Example

import pandas as pd

data = pd.read_sas('testdata4_nocompress.sas7bdat', format='sas7bdat', encoding='big5', chunksize=5000)

for d in data:
    print(d)

Issue Description

Hi teams, when I use read_sas to read my SAS dataset, it always occur segmentation fault in for loop

Expected Behavior

It should print every chunksize with 5,000 rows in for loop.

Are you able to share a SAS file to reproduce this issue?

Please see attachment, thank you.

When I read the entire file (without chunksize), I can re-producde the segfault on master.

With chunksize, I get a UnicodeDecodeError

File "pandas/pandas/core/strings/accessor.py", line 1795, in
f = lambda x: decoder(x, errors)[0]
UnicodeDecodeError: 'big5' codec can't decode byte 0xf0 in position 0: illegal multibyte sequence

I changed the Chinese test data into English, you can try again, thank you!

we could close this issue if there are relevant tests already added else need to add a test.
