     // situation. Check the line tables and build the arange table from this.
     SymbolContext sc;
     sc.comp_unit = dwarf->GetCompUnitForDWARFCompUnit(this);
@clayborg Any idea how to reproduce this code path? I expected test_lt as below would do, but debug_aranges is read from DIE even there. Is it (only) for backwards compatibility?
clang -c -gline-tables-only -o main_lt.o main.c
clang -c -gline-tables-only -o cu1_lt.o cu1.c
clang -gline-tables-only main_lt.o cu1_lt.o -o test_lt

+    return 0;

No worries, thanks for having a look.
