> I have a backend test that I know leaks memory. It isn't checked in anywhere, but I know from visual inspection that it does leak memory. However, when I compile with ASAN and run the test via ctest, LSAN doesn't detect the leak. Turning on verbose mode, I get this:
> {noformat}
> 54: Test command: /home/joemcdonnell/upstream/Impala/bin/run-jvm-binary.sh "/home/joemcdonnell/upstream/Impala/be/build/debug//runtime/memory-leak-test" "-log_dir=/home/joemcdonnell/upstream/Impala/logs/be_tests"
> 54: Environment variables:

> 54: Test timeout computed to be: 10000000
> ...
> 54: [==========] Running 1 test from 1 test case.
> 54: [----------] Global test environment set-up.

> The following tests passed:

> 100% tests passed, 0 tests failed out of 1
> {noformat}
> LSAN can detect some memory leaks, but this particular memory leak only gets detected if I also add ASAN_OPTIONS="detect_leaks=1". It looks like we intended that to be added, because we have it listed here in be/CMakeLists.txt:
> {noformat}
> FUNCTION(ENABLE_LSAN_FOR_TEST TEST_NAME)
>     SET_TESTS_PROPERTIES(${TEST_NAME} PROPERTIES ENVIRONMENT
>         "ASAN_OPTIONS=handle_segv=0 detect_leaks=1 allocator_may_return_null=1")
>     SET_TESTS_PROPERTIES(${TEST_NAME} PROPERTIES ENVIRONMENT
>         "LSAN_OPTIONS=suppressions=${CMAKE_SOURCE_DIR}/bin/lsan-suppressions.txt")
> ENDFUNCTION(){noformat}
> The second invocation overwrites the first rather than appending, so we only get LSAN_OPTIONS.
