Hello Kou,
Thank you for your further infomation, it's very helpful!
As you advised, we dived into our code and found that on any condition that
a CAST keyword passed to Arrow, it would throw out exception as below.
Attached is our source code, and our input is a SQL clause "SELECT
CAST(a.ID AS INTEGER) FROM MDS01."mds_work_team" a".
Would you help us a little out of our difficulty?
Thanks a lot in advance!

主题: Re: 回复: [DISCUSS][C++][JNI] libgandiva_jni.so fails to run on ARM platform
(but compilation successful)
Hi,
It seems that crashed at
https://github.com/apache/arrow/blob/apache-arrow-16.1.0/java/gandiva/src/main/cpp/jni_common.cc#L612
or
https://github.com/apache/arrow/blob/apache-arrow-16.1.0/java/gandiva/src/main/cpp/jni_common.cc#L616
.
Could you check your schema and expressions that are passed
to Projector::make()?
Thanks,
