The instance fixed here was found by Clang's undefined behavior sanitizer. It was found in the end-to-end tests. The interesting part of the stack trace is: be/src/util/bitmap.h:78:12: runtime error: null pointer passed as argument 1, which is declared to never be null /usr/include/string.h:62:79: note: nonnull attribute specified here #0 0x2ccb59b in Bitmap::SetAllBits(bool) be/src/util/bitmap.h:78:5 #1 0x2cb6b9e in NestedLoopJoinNode::ResetMatchingBuildRows(RuntimeState*, long) be/src/exec/nested-loop-join-node.cc:176:27 #2 0x2cb5ad6 in NestedLoopJoinNode::Open(RuntimeState*) be/src/exec/nested-loop-join-node.cc:90:43 Change-Id: I804f642f4be3b74c24f871f656c5147ee226d2c8 Reviewed-on: http://gerrit.cloudera.org:8080/11042 Reviewed-by: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenk...@cloudera.com> > UBSAN clean and method for testing UBSAN cleanliness > ---------------------------------------------------- > > Key: IMPALA-5031 > URL: https://issues.apache.org/jira/browse/IMPALA-5031 > Project: IMPALA > Issue Type: Task > Components: Backend, Infrastructure > Affects Versions: Impala 2.9.0 > Reporter: Jim Apple > Assignee: Jim Apple > Priority: Minor > > http://releases.llvm.org/3.8.0/tools/clang/docs/UndefinedBehaviorSanitizer.html > builds are supported after https://gerrit.cloudera.org/#/c/6186/, but > Impala's test suite triggers many errors under UBSAN.
