This also happens on mainline, see http://gcc.gnu.org/ml/gcc-testresults/2005-03/msg01267.html
This also occurs on hppa64-hp-hpux11.11 (4.1.0)
Just a guess, but I would suspect this is caused by the following change: 2005-03-16 Richard Henderson <rth@redhat.com> PR middle-end/15700 * varasm.c (struct alias_pair): Rename from struct output_def_pair. (alias_pairs): Rename from output_defs. (find_decl_and_mark_needed): Split out from assemble_alias. (do_assemble_alias): New. (assemble_output_def): Remove. (finish_aliases_1, finish_aliases_2): New. (process_pending_assemble_output_defs): Remove. (assemble_alias): Defer aliases for which we don't yet have a non-external decl for the target symbol. * passes.c (rest_of_decl_compilation): Register variables with cgraph. * cgraphunit.c (cgraph_finalize_compilation_unit): Use finish_aliases_1. * toplev.c (compile_file): Use finish_aliases_2 instead of process_pending_assemble_output_defs. * tree.h (finish_aliases_1, finish_aliases_2): Declare. (process_pending_assemble_output_defs): Remove.
