re PR lto/45018 (ICE: tree check: did not expect class 'type', have 'type' (record_type) in contains_placeholder_p, at tree.c:2749)
2010-07-21 Richard Guenther <rguenther@suse.de>
PR lto/45018
* tree.c (find_decls_types_r): Do not follow TREE_CHAIN
of TYPE_DECLs. Do not follow TYPE_NEXT_VARIANT,
TYPE_NEXT_PTR_TO, nor TYPE_NEXT_REF_TO or TYPE_CANONICAL.
* g++.dg/lto/20100721-1_0.C: New testcase.
