[ELF] Initialize Target before it may be dereferenced by findAux when reporting "duplicate symbol" error
for (InputFile *F : Files) Symtab->addFile<ELFT>(F); // if there is a duplicate symbol error ... Target = getTarget(); When parsing .debug_info in the object file (for better diagnostics), DWARF.cpp findAux may dereference the null pointer Target auto *DR = dyn_cast<Defined>(&File->getRelocTargetSym(Rel)); if (!DR) { // Broken debug info may point to a non-defined symbol, // some asan object files may also contain R_X86_64_NONE RelType Type = Rel.getType(Config->IsMips64EL); if (Type != Target->NoneRel) /// Target is null Move the assignment of Target to an earlier place to fix this.
