In the function update_all_relocations, the global all_relocations is not
initialized.
1829 static void
1830 update_all_relocations (size_t nentries)
1831 {
1832 size_t sz;
1833
1834 if (!do_got_section_contents)
1835 return;
1836
1837 if (!all_relocations_root)
1838 {
1839 sz = nentries * sizeof (elf_relocation);
1840 all_relocations_root = xmalloc (sz);
1841 all_relocations = all_relocations_root;
1842 all_relocations_count = nentries;
1843 }
1844 else
1845 {
1846 size_t orig_count = all_relocations_count;
1847 sz = (orig_count + nentries) * sizeof (elf_relocation);
1848 all_relocations_root = xrealloc (all_relocations_root, sz);
1849 all_relocations = all_relocations_root + orig_count;
1850 all_relocations_count += nentries;
1851 }
1852 memset (all_relocations, 0, nentries * sizeof (elf_relocation));
1853 }

But in function dump_relr_relocations, it is accessed.
2177 if (do_got_section_contents)
2178 {
2179 all_relocations[r].r_offset = where;
2180 all_relocations[r].r_name = rtype;
2181 all_relocations[r].r_symbol = NULL;
2182 all_relocations[r].r_type = reltype_relr;
2183 r++;
2184 }
