It looks like it was caused by:
-2005-08-26 Jakub Jelinek <jakub@redhat.com>
-
- PR rtl-optimization/23561
- * builtins.c (get_memory_rtx): Add LEN argument. If MEM_EXPR is
- a COMPONENT_REF, remove all COMPONENT_REF from MEM_EXPR unless
- at most LEN bytes long memory fits into the field.
- (expand_builtin_memcpy, expand_builtin_mempcpy, expand_movstr,
- expand_builtin_strncpy, expand_builtin_memset, expand_builtin_memcmp,
- expand_builtin_strcmp, expand_builtin_strncmp): Adjust callers.
Which means this is 4.0 regression too now.
