Anuj Phadke created IMPALA-7473:
-----------------------------------
Summary: Impala hits general protection fault.
Key: IMPALA-7473
URL: https://issues.apache.org/jira/browse/IMPALA-7473
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 2.13.0
Reporter: Anuj Phadke
DecimalValue does not seem to be 16 bytes aligned and impala hits a GPF. I
could only recreate this issue only with logging level set to 3.
Here is a recreation of this on Impala version - 2.13.0
