------- Comment #6 from matz at gcc dot gnu dot org 2009-12-19 02:33 ------- Ah, because the references to trees are not handled via the write_cache hashtable, but via the per-kind stream (in output_block.decl_state), which is not realloced on create_output_block, but only on lto_push/pop_out_decl_state. Unintuitive :)
