Work on IMPALA-11365 started by Daniel Becker. ---------------------------------------------- > Dereferencing null pointer in TopNNode > -------------------------------------- > > Key: IMPALA-11365 > URL: https://issues.apache.org/jira/browse/IMPALA-11365 > Project: IMPALA > Issue Type: Bug > Reporter: Daniel Becker > Assignee: Daniel Becker > Priority: Major > > In the constructor of TopNNode, if {{pnode.partition_comparator_config_}} is > NULL, we initialise {{partition_cmp_}} with a NULL pointer. However, when > initialising {{{}partition_heaps_{}}}, we dereference {{partition_cmp_}} > because {{ComparatorWrapper}} expects a reference. > This has so far not lead to a crash because in this case the comparator of > {{partition_heaps_}} is not used, but assigning a NULL pointer to a reference > is undefined behaviour. -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
