--- Comment #12 from Richard Biener <rguenth at gcc dot gnu.org> ---
OK, so C++ has
else if ((DECL_NAME (decl) == NULL_TREE)
&& TREE_CODE (decl) == NAMESPACE_DECL)
dump_decl (cxx_pp, decl, TFF_PLAIN_IDENTIFIER | TFF_UNQUALIFIED_NAME);
and thus "copes" with namespaces without a name. I wonder if we want
pubnames late at all. For darwin and other targets with "crippled"
early LTO support (read: no support) this means we'd not generate those
lookup entries.
Since we output_pubtables only from dwarf2out_finish (why?) we don't
get those into early debug. Sth to investigate.
The ICE can probably be fixed with the following - can you test that?
