We're hitting this now, not sure how we didn't before.
conntrack.i:
```
enum a { b } register_dccp();
void c();
void __attribute__((noreturn)) exit_error(enum a d) {
__builtin_va_end(0);
if (d)
c();
c();
__builtin_exit(1);
}
int main() { register_dccp(); }
```
libct_proto_dccp.i:
```
int a;
void exit_error();
void register_dccp() { exit_error(a); }
```
