    Description

      The tests TestCodegenCache.

      {test_codegen_cache_with_asm_module_dir,test_codegen_cache_with_perf_map}

      introduced by IMPALA-12260 were added to ensure we don't crash because of a use-after-free. However, use-after-free is undefined behaviour and does not guarantee a crash, so the tests don't necessarily crash without the fix of IMPALA-12260. We should find a way to make these tests detect the conditions that lead to this use-after-free.
