Summary: While parsing a childless compile unit DIE we could crash if the DIE was followed by any extra data (such as a superfluous end-of-children marker). This happened because the break-on-depth=0 check was performed only when parsing the null DIE, which was not correct because with a childless root DIE, we could reach the end of the unit without ever encountering the null DIE. If the compile unit contribution ended directly after the CU DIE, everything would be fine as we would terminate parsing due to reaching EOF. However, if the contribution contained extra data (perhaps a superfluous end-of-children marker), we would crash because we would treat that data as the begging of another compile unit. This fixes the crash by moving the depth=0 check to a more generic place, and also adds a regression test.
