The linker crashes during eh-frame parsing on ppc64. The bug was introduced by
this change:
2007-12-15 Richard Sandiford <[EMAIL PROTECTED]>
* 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.
