[schwab at suse dot de]

The linker crashes during eh-frame parsing on ppc64.  The bug was introduced by 
this change:

2007-12-15  Richard Sandiford  <address@hidden>

        * elf-bfd.h (eh_cie_fde): Add u.fde.next_for_section and
        u.cie.gc_mark.
        (bfd_elf_section_data): Add fde_list.
        (elf_fde_list): New macro.
        (elf_obj_tdata): Add eh_frame_section.
        (elf_eh_frame_section): New macro.
        (_bfd_elf_gc_mark_reloc): Remove last parameter.
        (_bfd_elf_gc_mark_fdes): Declare.
        * elf-eh-frame.c (_bfd_elf_get_eh_frame_sec_info): Chain the FDEs
        for each input section.
        (mark_entry, _bfd_elf_gc_mark_fdes): New functions.
        * elflink.c (_bfd_elf_gc_mark_reloc): Remove is_eh parameter.
        (_bfd_elf_gc_mark): Update call accordingly.  Mark the relocations
        againts the section's FDEs.  Don't mark the bfd's elf_eh_frame_section.
        (bfd_elf_gc_sections): Parse each input bfd's .eh_frame before
        marking any input sections.  Remove the current EH handling.
        * section.c (bfd_section): Remove gc_mark_from_eh.
        * ecoff.c (bfd_debug_section): Update initializer accordingly.

The most likely candidate is the change in bfd_elf_gc_sections.
