This one uncalled function produced 3.65k of binary output? I suppose that's not
a static build so the linker didn't get a chance to eliminate it yet?

To clarify, I am using content_shell executable on my linux(64 bit) desktop and
size change was like below. :)

Oh, I missed one thing to answer. :)
content_shell depends on content_shell_lib and the type of it is static_library.
