Confirmed.

252       else if (code == GIMPLE_LABEL)
253         gcc_assert (emit_label_in_global_context_p (gimple_label_label
(stmt))
254                     || DECL_CONTEXT (gimple_label_label (stmt)) ==
fn->decl);

DECL_CONTEXT seems to be off.  Not sure if we ever assert this during regular
verification though (so might be a bug without LTO as well).
