I get

DIE    0: DW_TAG_member (f821cdb0)
  abbrev id: 0 offset: 0 mark: 0
  DW_AT_name: "is_specialized"
  DW_AT_decl_file:
"/var/gcc/reghunt/pch-segv/36684/sparc-sun-solaris2.12/sparcv9/libstdc++-v3/include/limits"
(0)
  DW_AT_decl_line: 385
  DW_AT_type: die -> 0 (fb6a4c60)
  DW_AT_external: 1
  DW_AT_declaration: 1
  DW_AT_const_value: floating-point or vector constant
  DW_AT_const_expr: 1

for the innermost call to gt_pch_nx_die_struct.
