> In IMPALA-14493, the TcmallocMetric::BYTES_IN_USE metric is used to safeguard memory usage in admissiond, preventing potential OOM issues. However, in ASAN or TSAN builds, the code uses SanitizerMallocMetric::BYTES_ALLOCATED instead of TcmallocMetric::BYTES_IN_USE (as shown here [https://github.com/apache/impala/blob/2688e30ae51d90de6d9e061b75a2f7bc4af24892/be/src/util/memory-metrics.cc#L113], ). As a result, using an uninitialized metric TcmallocMetric::BYTES_IN_USE, leading to a crash.
