REGR: pd.read_csv segfaults with 1.2 (has worked since before pandas 1.0) · Issue #38753 · pandas-dev/pandas (original) (raw)

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of pandas.
• (optional) I have confirmed this bug exists on the master branch of pandas.

Code Sample, a copy-pastable example

Wish I could give more information, but this is all I have (not sure I can share the input data):

 Fatal Python error: Segmentation fault

  File "/usr/local/lib/python3.7/site-packages/pandas/io/parsers.py", line 605 in read_csv

Once I added the pin pandas<1.2 everything works again.
