[PATCH 6/9] test-tool json-writer: fix memory leaks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fix memory leaks introduced with these tests in
75459410edd (json_writer: new routines to create JSON data,
2018-07-13), as a result we can mark a test as passing with
SANITIZE=leak using "TEST_PASSES_SANITIZE_LEAK=true".
