Ben Kietzman created ARROW-11595: ------------------------------------ Summary: [C++][NIGHTLY:test-conda-cpp-valgrind] GenerateBitsUnrolled triggers valgrind on uninit output Key: ARROW-11595 URL: https://issues.apache.org/jira/browse/ARROW-11595 Project: Apache Arrow Issue Type: Bug Components: C++ Reporter: Ben Kietzman Assignee: Ben Kietzman Fix For: 4.0.0
https://github.com/ursacomputing/crossbow/runs/1877315066#step:6:2818 Comparison kernels generate an output bitmap for all array values, including those masked by a null bit. This should be fine since the indeterminate bits are also masked in the output but valgrind still triggers on the branching in GenerateBitsUnrolled. -- This message was sent by Atlassian Jira (v8.3.4#803005)
