Please try to figure out which patch broke this and adjust accordingly the
component, because evidently this isn't a library proper issue (eh, nothing
substantive went in!)

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.

cppcheck fails to compile because of this bug.

cli/cmdlineparser.o: In function `~basic_istream':
/usr/include/c++/4.8.0/istream:106: undefined reference to `construction vtable

it says that 'construction vtable for std::basic_istream<char,

cannot be found, but it exists.

I suspect it would be duplicate of 54314.

Still broken on both i386-pc-solaris2.9 and sparc-sun-solaris2.9 as of
20120914 (r191294).

I don't see such a failure in
http://gcc.gnu.org/ml/gcc-testresults/2012-11/msg00497.html , so fixed now?

Right, seems it got fixed between 20120921 and 20120928.
