            Bug ID: 38918
           Summary: lld crashes (nullptr derference) when linking kernel
                    with --icf=all
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org
          Reporter: phosek at chromium.org
                CC: llvm-bugs at lists.llvm.org

It's a null pointer crash in lld::elf::InputSection::copyRelocations:

=>      P->r_addend = Sym.getVA(Addend) - Section->getOutputSection()->Addr;

Looks like getOutputSection returned nullptr.
