Since the information about the memory +# region covered by a comp_unit is only determined at link time, the low/high +# addresses in the .debug_info section and the line addresses in the .debug_line +# section are computed by generating relocs against known symbols in the object +# code. +# +# When the undefined reference is detected, the relocs in the dwarf2 +# debug sections have not yet been resolved, so the low/high addresses and the +# line number address are all set at zero.
