----------------------------------
Assignee: Zhenglin Tao (was: Ruilong Huo)
> Core dump in sub-transcation rollback
> -------------------------------------
>
> Key: HAWQ-1803
> URL: https://issues.apache.org/jira/browse/HAWQ-1803
> Project: Apache HAWQ
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.0.0.0
> Reporter: Zhenglin Tao
> Assignee: Zhenglin Tao
> Priority: Major
>
> For error handling on analyzeRelation failure in analyzeStmt,
> RollbackAndReleaseCurrentSubTransaction would be called and finally
> result in AtEOSubXact_SPI for resource release.
> However, the sub-transaction ID of the ANALYZE statement does not match
> that of the original SPI invoke. And this would result in an early
> release of the SPI's memory context, leading to memory corruption when
> there is still any other queries following the ANALYZE statement.
