start_type lazy didn't reconnect. dump core.

[hakofugu41]

Hello,
I am trying to use lazy option, but mosquitto crashed.
Then, dumps core.

ENV:
CentOS 6.7
mosquitto version 1.4.8

Figure:
mosquitto_pub --send message--> mosquitto(A) --bridge--> mosquitto(B)

I did these steps on my PC. (One host only)

1.Execute mosquitto(B)
$ mosquitto -v

2.Execute mosquitto(A).
Connect mosquitto(A) and mosquitto(B).
$ mosquitto -c start_type.conf
(The contents of start_type.conf are below)

3.Interrupt mosquitto(B) with Ctrl+C.

4.Try to reconnect mosquitto(A) and mosquitto(B)
$ mosquitto -v
Because of threshold option, not reconnected.

5.Send message to mosquitto(A)
$ mosquitto_pub -t /topic/A -m test1 -p 1884

6.Resend message to mosquitto(A)
$ mosquitto_pub -t /topic/A -m test2 -p 1884

7.mosquitto(A) carashes. Then, dumps core files.
Logs:

I have tried with mosquitto 1.4.10 and show the same behavior.

I've been able to reproduce this thanks to your instructions. I've pushed a fix to the "fixes" branch which will either end up in 1.4.11 or 1.5.

Thanks very much for reporting it!
