We disabled the range test for the valgrind + clang combination. asan still tests it and reports no problems.
I took a look at the glib source - the allocation is related to global state inside glib.
I took some time but could not figure why it is fine with glib 2.50 on stretch and not with glib 2.42 on jessie. I also made sure that the present valgrind suppression rules do not mask the leak on stretch.
After all cleanup is fine with the later version of glib. I created PR #1875 which updates the supression rules for this instance.
