I guess its inside netlink_parse_concat_expr()?
Things are already wrong when it enters there.
if (left->len > right->len &&
expr_basetype(left) != &string_type)
My guess is that left is 1 and right 8?
Could also be a 0-length due to missing round_up(), hard to tell
without knowing the actual value.
