Seems like an error introduced by this patch:

2003-05-13  Jason Merrill  <jason@redhat.com>

        Implement expression temporary optimization.
        * gimplify.c (gimplify_ctx): Add temp_htab field.
        (push_gimplify_context): Initialize it.          
        (pop_gimplify_context): Destroy it.
        (simplify_expr): If there's no internal postqueue, generate an
        expression temporary.
        (gimple_tree_hash, gimple_tree_eq): New fns.
        (create_tmp_from_val, lookup_tmp_var): New fns.
        (get_formal_tmp_var): New fn.
        (internal_get_tmp_var): New fn.
        (get_initialized_tmp_var): Use it.
        * tree-simple.h: Declare it.
