[jira] [Created] (HAWQ-1803) Core dump in sub-transcation rollback

Zhenglin Tao created HAWQ-1803:
----------------------------------

             Summary: 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
            Reporter: Zhenglin Tao
            Assignee: Ruilong Huo


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.
