Jim Apple has uploaded a new patch set (#3). Change subject: IMPALA-5031: Set DiskIoMgr::ScanRange::is_cancelled_ before read ......................................................................
IMPALA-5031: Set DiskIoMgr::ScanRange::is_cancelled_ before read Reading a uninitialized memory as a boolean is undefined behavior when it isn't the bit pattern for true or false. Clang's undefined behavior sanitizer caught is_cancelled_ being used before being initialized; this patch also initializes the other booleans in DiskIoMgr::ScanRange to prevent similar undefined behavior.
