It can happen only from the line:
m_die_array.back().SetEmptyChildren(true);
In the case DW_TAG_compile_unit has DW_CHILDREN_yes but there is only 0 (end of
list, no children present). Therefore the assertion can fortunately happen only
with a hand-crafted DWARF or with DWARF from some suboptimal compilers.
