free_frec looks like this now:
static void free_frec(struct frec *f)
{
  if (f->sentto == NULL) {
    my_syslog(LOG_WARNING, "free_frec break");
    return;
  }
  ...

In my humble testing I haven't encountered the message so far, but I
suspect the issue is timing dependent.

There's no gdb nor space for it on this device itself. But I'll check
if openwrt exposes some option to save coredumps.
