Hi Sven, I've been trying to reproduce it with your config but I didn't succeed. I also looked at the file after the preprocessor and it looked good: ret = ({ __builtin_expect(!!(ops->match == fib6_rule_match), 1) ? fib6_rule_match(rule, fl, flags) : ops->match(rule, fl, flags); }) Note that fib4_rule_match doesn't appear as the CONFIG_IP_MULTIPLE_TABLES is not there. Could you share more details on how you're compiling it and what compiler you're using??
