The following patches might be the cause:

+
+       PR middle-end/20225
+       * cgraph.c (cgraph_mark_reachable_node): Assert that it is not called
+       too late.
+       * varasm.c (find_decl_and_mark_needed): Mark needed only when not
+       called too late.

+       * tree-into-ssa.c (find_idf): Use VEC_quick_push instead of
+       VEC_safe_push.

+2005-03-18  Paolo Bonzini  <bonzini@gnu.org>
+
+       * combine.c (gen_binary): Remove.
+       (known_cond, simplify_shift_const, find_split_point,
+       combine_simplify_rtx, simplify_if_then_else, simplify_set,

+       simplify_and_const_int, simplify_shift_const, gen_lowpart_for_combine,

+       (distribute_and_simplify_rtx): New function.

+
+       * tree-cfg.c (fold_cond_expr_cond): Use boolean types for condition.
+
+       * cgraph.c (cgraph_remove_node): Avoid loop in code deciding whether 
+       function body should be released; do not proactively release function
+       bodies in non-unit-at-a-time mode.
+

+2005-03-18  Kazu Hirata  <kazu@cs.umass.edu>
+
+       * builtins.c (fold_builtin_bitop): Take decomposed arguments
+       of CALL_EXPR.
+       (fold_builtin_1): Update a call to fold_builtin_bitop.
+
+       * builtins.c (fold_builtin_signbit): Take decomposed arguments
+       of CALL_EXPR.
+       (fold_builtin_1): Update a call to fold_builtin_signbit.

Do you know if this happens on the 4.0 branch also, if it does not it removes the patch for "PR middle-
end/20225", otherwise that is the patch which caused it as no other patch went in both branches?

I almost this is caused by a copy and pasto with the combine patch.
