The -# structures also index into other structures held in the .debug_line section -# and together they can translate memory locations back into file/function/line -# number addresses in the source code. 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.
