abfd->section_count unexpectedly changes between 218 and 248 in:
150 bfd_simple_get_relocated_section_contents (bfd *abfd,
[...]
218 saved_offsets = malloc (sizeof (struct saved_output_info)
219 * abfd->section_count);
[...]
230 _bfd_generic_link_add_symbols (abfd, &link_info);
[...]
248 bfd_map_over_sections (abfd, simple_restore_output_info, saved_offsets);
_bfd_generic_link_add_symbols increases section_count
and simple_restore_output_info later reads unallocated part of saved_offsets.
