```
The assert we fail is almost certainly due to the flow being freed:
```
struct pf_result *pay_flow_finished_adding_gossip(struct pay_flow *pf)
{
assert(pf->state == PAY_FLOW_FAILED_GOSSIP_PENDING);
```

I am doing to add more more debugging, but sent here is 0. Document that clearly, and put a real value in sent. Also: since we already sub 1 msat from x, amount_msat_less_eq should be amount_msat_less (it may be equal to our min, in theory). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
