--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed everywhere with the reduced testcase (the pasted one misses a line).
We run into
tree
lto_symtab_prevailing_virtual_decl (tree decl)
{
...
gcc_checking_assert (!type_in_anonymous_namespace_p (DECL_CONTEXT (decl))
&& DECL_ASSEMBLER_NAME_SET_P (decl));
where type_in_anonymous_namespace_p (DECL_CONTEXT (decl)) is true.
TYPE_STUB_DECL is
