SIGSEGV in ld at elflink.h:5500


I started trying to get dwarf2 eh working on hppa64-hp-hpux.  I am
seeing a segmentation fault in gld linking the libstdc++-v3 shared
library.  This is the section data which causes the fault:

(gdb) p *s
$2 = {name = 0x8000000000240035 ".gnu.linkonce.t._ZTv0_n24_NSdD1Ev", id = 478, 
  index = 46, next = 0x8000000000246900, flags = 1049143, user_set_vma = 1, 
  reloc_done = 0, linker_mark = 0, linker_has_input = 0, gc_mark = 0, 
  segment_mark = 0, vma = 0, lma = 0, _cooked_size = 56, _raw_size = 56, 
  output_offset = 0, output_section = 0x8000000000005340, alignment_power = 3, 
  relocation = 0x0, orelocation = 0x0, reloc_count = 1, filepos = 127080, 
  rel_filepos = 204960, line_filepos = 0, userdata = 0x0, contents = 0x0, 
  lineno = 0x0, lineno_count = 0, entsize = 0, comdat = 0x0, 
  moving_line_filepos = 0, target_index = 0, used_by_bfd = 0x8000000000247698, 
  constructor_chain = 0x0, owner = 0x80000000000d7998, 
  symbol = 0x8000000000247638, symbol_ptr_ptr = 0x80000000002468c8, 
  link_order_head = 0x0, link_order_tail = 0x0}
(gdb) p *s->output_section
$3 = {name = 0x40000000000b0550 "*ABS*", id = 2, index = 0, next = 0x0, 
  flags = 0, user_set_vma = 0, reloc_done = 0, linker_mark = 0, 
  linker_has_input = 0, gc_mark = 1, segment_mark = 0, vma = 0, lma = 0, 
  _cooked_size = 0, _raw_size = 0, output_offset = 0, 
  output_section = 0x8000000000005340, alignment_power = 0, relocation = 0x0, 
  orelocation = 0x0, reloc_count = 0, filepos = 0, rel_filepos = 0, 
  line_filepos = 0, userdata = 0x0, contents = 0x0, lineno = 0x0, 
  lineno_count = 0, entsize = 0, comdat = 0x0, moving_line_filepos = 0, 
  target_index = 0, used_by_bfd = 0x0, constructor_chain = 0x0, owner = 0x0, 
  symbol = 0x80000000000050d8, symbol_ptr_ptr = 0x8000000000005338, 
  link_order_head = 0x0, link_order_tail = 0x0}

This is the code that faults:

                    sym.st_shndx =
		      elf_section_data (s->output_section)->this_idx;

The "elf_section_data" macro returns a null pointer.

Anybody got any ideas on what's causing this?
