--- Comment #1 from Sergei Trofimovich <slyfox at inbox dot ru> ---
Sometimes the crash happens before an assert.

valgrind reports the following first erroneous dereference:

==8230== Invalid read of size 4
==8230==    at 0x8F116A: _bfd_sparc_elf_create_dynamic_sections
(elfxx-sparc.c:1223)
==8230==    by 0x6922DF: _bfd_elf_link_create_dynamic_sections (elflink.c:362)
==8230==    by 0x695401: elf_add_dt_needed_tag (elflink.c:3532)
==8230==    by 0x697DAE: elf_link_add_object_symbols (elflink.c:4208)
==8230==    by 0x697DAE: bfd_elf_link_add_symbols (elflink.c:5723)
==8230==    by 0x2CD740: load_symbols (ldlang.c:2881)
==8230==    by 0x2CE184: open_input_bfds (ldlang.c:3330)
==8230==    by 0x2D0410: lang_process (ldlang.c:7182)
==8230==    by 0x2BE3C6: main (ldmain.c:438)

Which is:

  bfd_boolean
  _bfd_sparc_elf_create_dynamic_sections (bfd *dynobj,
                                          struct bfd_link_info *info)
  {
    struct _bfd_sparc_elf_link_hash_table *htab;

    htab = _bfd_sparc_elf_hash_table (info);
/*1218:*/ BFD_ASSERT (htab != NULL);

    if (!_bfd_elf_create_dynamic_sections (dynobj, info))
      return FALSE;

/*1223:*/ if (htab->is_vxworks)
