A reghunt identified the following patch as the culprit:

2012-05-18  Jan Hubicka  <jh@suse.cz>

    * cgraphbuild.c (record_reference): Update.
    * lto-cgraph.c (lto_output_varpool_node): External vars
    are not in other partition even if they are not output
    in current partition.
    * gimple-fold.c (can_refer_decl_in_current_unit_p): Take FROM_DECL
    argument; fix.
    (canonicalize_constructor_val): Take FROM_DECL argument.
    (fold_ctor_reference, fold_string_cst_ctor_reference,
    fold_array_ctor_reference, fold_nonarray_ctor_reference,
    fold_ctor_reference): Likewise.
    (fold_const_aggregate_ref_1, gimple_get_virt_method_for_binfo): Update.
    * gimple.h (gimple_fold_builtin): Likewise.

Jan, what additional information do you need to investigate?

Thanks.
  Rainer
