---------------------------------------

             Summary: double-free memory issue in unifiedbetests if it's built in dynamically linked mode
                 Key: IMPALA-12915
                 URL: https://issues.apache.org/jira/browse/IMPALA-12915
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
            Reporter: Quanlong Huang


I have a pretty simple change that just adds one new metric in common/thrift/metrics.json: [https://github.com/stiga-huang/impala/commit/3972aed68428b3f307e823f49a2700c1a98aa3b3]
It breaks the clang-tidy job in the step of running "unifiedbetests --gtest_list_tests".

The job builds Impala using the -so option which means dynamically link executables (default is static). I'm able to reproduce the issue locally. Using gdb, I can see the process crashed by a memory issue:

[~boroknagyz] found that upgrading gtest to 1.14 resolves the issue. The current gtest version is 1.6. I tried building with ASAN and also build the underlying gtest-1.6 with ASAN. The run then shows the memory issue:

Note that I have to remove the definition of "THttpTransport::CRLF_LEN" in be/src/transport/THttpTransport.cpp to avoid an ODR violation issue.

libkudu_test_util.so wants to delete a vector that is already deleted by gtest.

In the static build, we are fine since there are no libkudu_test_util.so or libkudu_util.so.
