pitrou opened a new issue, #43211: URL: https://github.com/apache/arrow/issues/43211
### Describe the bug, including details regarding any error messages, version, and platform. Some of the decimal benchmarks access their benchmark data in strides, without checking that the accesses fall withing bounds. Example here, where `kValueSize` (10) is actually not a multiple of 4: https://github.com/apache/arrow/blob/5e451d85d7269d3fb9c7eaab06caece5718c40e5/cpp/src/arrow/util/decimal_benchmark.cc#L89-L98 This manifests in crashes on some of the macOS benchmark machines, and the issue can be reproduced locally using Valgrind: ```console $ ARROW_DEFAULT_MEMORY_POOL=system valgrind <build dir>/relwithdebinfo/arrow-decimal-benchmark --benchmark_repetitions=6 --benchmark_min_time=0.050000s ``` ### Component(s) C++ -- This is an automated message from the Apache Git Service.
