How to reproduce:

1.check out latest code, 5922ba762a
2.compile with asan, 
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fsanitize=address  -g")
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fsanitize=address  -g")
3.run ./mp4dump --verbosity 3 --format text  poc1

poc1.zip

You can see the asan information below:
