> Key: ARROW-11427
> URL: https://issues.apache.org/jira/browse/ARROW-11427
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++, Python
> Environment: Windows Server 2012 Datacenter, Azure VM (D2_v2), Intel Xeon Platinum 8171m
> Reporter: Ali Cetin
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0

> Time Spent: 20m
> Remaining Estimate: 0h

> *Update*: Azure (D2_v2) VM no longer spins-up with Xeon Platinum 8171m, so I'm unable to test it with other OS's. Azure VM's are assigned different type of CPU's of same "class" depending on availability. I will try my "luck" later.
> VM's w/ Xeon Platinum 8171m running on Azure (D2_v2) start crashing after upgrading from pyarrow 2.0 to pyarrow 3.0. However, this only happens when reading parquet files larger than 4096 bits!?
> Windows closes Python with exit code 255 and produces this:
