Hello 정복득,
thanks for reporting. I gave both issues a go.

I could not reproduce this with current Genode master. The code [1]
produces the expected output:
[init -> test-ll_var] result of test_buf:1234567801234
[init -> test-ll_var] llu_var:1234567801234
Could you please test again with my test branch/the attached patch?

This indeed seems to be a bug in Genode and I opened a new issue
https://github.com/genodelabs/genode/issues/275 using this code [2].
We will investigate this further and report here.
[1] https://github.com/chelmuth/genode/tree/test-ll_var or
attachment test-ll_var.patch
[2] https://github.com/chelmuth/genode/tree/test-sstream or
attachment test-sstream.patch
