SIGSEGV. x86_64 EFI COFF section hack.

[Christian Melki]

Hi.

Tried linking a 64-bit EFI app (U-Boot) which resulted in a SEGV in
ld.bfd (binutils 2.37):

 Program received signal SIGSEGV, Segmentation fault.
0x00005555555d1a8f in elf_x86_64_finish_dynamic_sections
(output_bfd=0x5555557fefa0, info=0x5555557fa140 <link_info>) at
/src/binutils/bfd/elf64-x86-64.c:4676
4676            ->this_hdr.sh_entsize = htab->plt.plt_entry_size;
(gdb) bt

(gdb) p (struct bfd_elf_section_data
*)(htab->elf.splt->output_section)->used_by_bfd
$3 = (struct bfd_elf_section_data *) 0x0

Found elf_i386_fake_section handling the COFF reloc object but no
similar function for x86_64. Am I missing something here? Maybe the SEGV
is related to something else?
